   CP3 calculation

How do I calculate CP3?

CP3 is a parameter which helps to assign structure and stereochemistry by comparing experimental and calculated NMR spectra.

The calculation of CP3 is a three step process:

  1. Enter data (separated by commas in each line)
  2. Assign resonances (optional - the program will try to do this for you)
  3. Calculate CP3
The program calculates which calculated spectrum is most likely to correspond to each experimental spectrum and gives a measure of its confidence in its conclusion.
