According to Wikipedia:

An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.[1] This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

 

 

String theory describes particles as vibrating strings; in other words, strings with waves. The orbital wave-like function and the string vibration apparently interact, because adding energy to an electron causes it to change orbital, and possibly vibrate more energetically. What can be deduced about string theory from observing these interactions in various atoms.

Just about nothing. The energy scales involved are so different.

 

One particular vibrational mode of a string will correspond to an electron in the low energy limit. As far as atomic physics, or indeed high energy physics today, the standard model is what we see. Loosley, the strings are too small for us to detect their presence in atomic physics.
