nemzy Posted January 28, 2005 Share Posted January 28, 2005 how do we know if a molecule is optically active? does it have to do something about R,S configurations? I have no idea, what it is...and how to know whether a molecule is optically active or not thanks Link to comment Share on other sites More sharing options...
Crash Posted January 28, 2005 Share Posted January 28, 2005 Usually assymetric molecules rotate plane polarized light, so they are refered to as "optically active" Link to comment Share on other sites More sharing options...
goodyhi11 Posted January 31, 2005 Share Posted January 31, 2005 i remembered dr.feynmen said something about active molecules. It has a 2 percent possiblility on every rotation of the electron orbiting proton. And a T + V transaction between the R + T. but later we discovered that electron do not go eliptical order or in circular path. Link to comment Share on other sites More sharing options...
YT2095 Posted January 31, 2005 Share Posted January 31, 2005 it all depends on what you mean by Opticaly Active? if you`re talking photo-chemical (like Silver Chloride used in photography), then the light acts almost as a catalyst. if you mean things that Fluorescent(sp), Phosphorescent(sp) or Laze then it`s to do with Ionisation levels. things like LCD screens are different though, thats an electro-chem reaction, it aligns molecules in a polar fashion, to either allow existing light to pass or Not as the case may be.
