thanks

Dave, can you post nuclear equations with this chemistry LaTeX? I can't seem to work out how

 

Cheers,

Sorry, I hadn't noticed your post until a few minutes ago

 

I'm looking at ways of enabling people to draw diagrams on here with something like pstricks or similar. If you find any LaTeX packages that you think would be useful, then please let me know.

Thanks for the reply Dave, if I find one I will be shure to let you know!

Hi nice guys,

I've just installed mimeTeX on my Server, and it's running well. Now, I wanna add mhchem to, like here, but I dunno how to deal with this matter. It's kind of you to give me some instructions.

 

Thank you very much for your kind attention.

When you click on the images for their code, the link "Click here to see a LaTeX guide." points to nowhere.

I teach high school chemistry and would like to use LaTex to create images I could insert into WORD documents that I then can print on paper or transparencies.

 

Can I use this facility in an XP environment with WORD documents? If so, where do I get a copy of the program to download to my workstation?

 

I do not have access to Linus and would rather not have to. I really must use XP.

It's possible (but complicated). The easiest way would be to skip Word entirely and write your documents with LaTeX (as it is a typesetting system).

 

There's also a Microsoft Equation Editor that works natively with Word: http://www.microsoft.com/education/insertequation.mspx

isnt latex found in ruber johnnys?

You need to be bant, imo

What's going on? All math [math]E=mc^2[/math] is generating LaTeX Error: Syntax error , LaTeX Error: One or more directories do not exist, and similar problems.

That´s probably a problem stemming from the changes to the page that are currently done. Let´s hope it´ll be fixed, soon.

Looks like we lost some stuff during the upgrade. The LaTeX folder was moved to the wrong spot...

 

Fixed it. LaTeX images will have to regenerate now (they're usually cached), but they should work.

 

edit: right, I lied. Let me see what I can do.

 

[math]x^2[/math]

[math]E=mc^2[/math]

dave, it looks like mhchem refuses to work -- all other math works correctly.

 

I'll pass the ball to you know, since you know the LaTeX stuff.

hi this is jasmine.iam really struggling to find the sourcecode in LaTex for chemical equations and chemical bond diagrams.when i type \ce{H2O} nothing is coming up.pl help me.thanks.

Hi!

 

This is the author of the mhchem LaTeX package. It's nice to see people using my work. Have a lot of fun with it!

 

If you have any feedback (good or bad), please feel free to contact me. In particular, I would be very interested if you find a chemical expression that mhchem does not support currently.

 

Hey, thanks for the package, sure helps me out. One thing though..how can I write radical-type reactions: for example:

 

\ce{Rf-CF2COOH + \cdot\ce{OH} -> Rf-CF2\cdot}\ce{+ CO2 + H2O}

is the only way to write it because with the \reaction command, every dot from the radicals would tranform the OH for instance in italic style like it s not a reaction anymore, so I decided to use the \ce function, it works but... I cant label it as an equation

 

any ideas?

 

thanks

You have to open it with tag --> [ce] and close it with tag --> [/ce].

 

 

Like this:

[ce]Rf-CF2COOH + \cdot{OH} -> Rf-CF2\cdot + CO2 + H2O[/ce]

 

 

That will output the following:

 

[ce]Rf-CF2COOH + \cdot{OH} -> Rf-CF2\cdot + CO2 + H2O[/ce]

I did this but you see the OH radical is italic...cant seem to have it all...what do you think?

If it were me, I'd just end the CE section after your cdot then begin it again before the OH... Like this:

 

 

[ce]Rf-CF2COOH + \cdot[/ce][ce]{OH} -> Rf-CF2\cdot + CO2 + H2O[/ce]

 

 

 

[ce]Rf-CF2COOH + \cdot[/ce][ce]{OH} -> Rf-CF2\cdot + CO2 + H2O[/ce]

yeah exactly, that s what i thought...the thing is...how do I label all this now as a reaction =)

thanks for the feedback. why do you use php commands for latex? where do you edit latex?

the best thing i have now is this:

 

\reaction{Rf-CF2COOH + \cdot\ce{OH} -> Rf-CF2\cdot + CO2 + H2O}

 

with \reaction defined as:

 

\newcommand\reaction[1]{\begin{equation}\ce{#1}\end{equation}}

\newcommand\reactionnonumber[1]%

{\begin{equation*}\ce{#1}\end{equation*}}

 

so it is labelled and not italic. BUT now the probleme is the + after the \cdot in.......\cdot + CO2 i get a plus like a cation sign

 

but that s the best so far, would you know a command to get the + back on the ground like a normal one?

OK if anybody needs that, i found a way, tricky but it works: just make sure the cdot is isolated like that, it looks then OK, it s labelled, etc.. thanks for your help.

 

\reaction{Rf-CF2COOH + \cdot\ce{OH} -> {Rf-CF2\cdot} + CO2 + H2O}

H2SO4

 

Basically, you type whatever comes into your head. LaTeX sorts all the formatting out for you. Let's try a harder example: what about something like an ion H+? Again, type whatever comes into your head:

 

H+

 

Click on the image to see the code that generated it.

 

I should point this out: you need to encapsulate everything in math tags:

 

[math ]\cf{SUPErB}[/math]

Testing Testing!

 

[ce] CuCl2 + Na2CO3 -> CuCO3 + 2NaCl [/ce]

 

[ce] CH3CH2OH ->[{alcohol dehydrogenase}] CH3CHO + H2 [/ce]

 

[ce] Mg + 2H2O -> Mg(OH)2 + H2 [/ce]

 

[ce] Cu + Zn^2+ -> Cu^2+ + Zn [/ce]

 

[ce] FeS + 2HCl -> FeCl2 + H2S [/ce]

 

[ce] H2O2 + SO2 -> H2SO4 [/ce]

 

[ce] Acetate + CoA- SH + ATP <=>[{acetyl-CoA synthetase}] Acetyl-S-CoA + AMP + PPi [/ce]

 

[ce] HCl + H2O <=> H3O+ + Cl- [/ce]

 

[ce] -OOCCH2CH2COO- ->[{succinate dehydrogenase}] -OOCCH=CHCOO- + H2 [/ce]

 

[ce] {{x}}_ CuSO4 + 4NH3 -> Cu_{{x}}(NH3)4(SO4)_{{x}} [/ce]

 

[ce] RNH2 + CO2 <=> RNHCOOH <=> RNHCOO- + H+ [/ce]

 

Absolutely brilliant; and a fair bit easier to play with than its predecessor, which in itself is a much needed improvement; awesome job Dave! I do believe that reputation points are in order...

latex problems

theo, this isn't new, the last post, prior to aadhar's was in april. I'm sure dave won't mind some extra rep anyhow, though

Really? Meh, what the hell- I never was quite good with latex, or dates and times. I thought it may have been new as the layout seemed different, if i vaguely recall. Alas!

Hey guys,

I'm not really new to LaTex, I have already written sveral reports.

 

But for my next report I have a new challenge:

I have a compound, a metal komplex, that has a top and a bottom center who are connected. Imagine something like C6H10 and to of the carbons are connected with a platinumdicloride....

 

PtCl2CH((CH2)2)2CH and now I want to show, that the Pt is connected to both carbons. So I have seen a longer "bond" on the top the the formula, that goes from the Pt to the last CH!

 

Hope u got it

 

Roy
