JNMRPen - C-13 NMR Shift Predictor

JNMRPen© is a java® applet for estimating C-13 NMR shifts. To make a prediction draw an organic molecule using JNMRPen©'s point and click menu based interface. Then click the NMR Shifts button to compute.

JNMRPen is a simplified version of NMRPen©, ChemPen Software's powerful NMR shift prediction application. ChemPen Software creates chemical drawing, molecular mechanics and NMR shift software for Windows® PCs. NMRPen© includes a 73000+ editable database of C-13 and H-1 chemical shifts and supports heteronuclei.
