Shift: NMR Chemical Shift Interpretation
This application uses chemical shift substituent constants to predict the chemical
environment for your input chemical shift. Only aliphatic shifts are
available. Because many substituent constants
are similar, hundreds of different substitutent patterns will give the same chemical
shift. Therefore, one chemical shift will match many possible chemical
environments. To decrease the number of possible substituents, information
from IR and mass spectrometry are necessary. Fill in as many of the fields
below as you can. If there are default values, change the defaults to be
as specific as possible. The more information you provide, the more likely
you are to receive a unique result. If you don't know, leave the field blank.
