INTRODUCTION

ChemPen is the low cost, easy to use tool for chemists, educators and students who need to create create drawings for chemical documentation. ChemPen+ includes everything in ChemPen plus basic C-13 chemical shift prediction.Drawing with ChemPen is done with menus, mouse clicks and simple editors. Drawings can be pasted into Windows® graphics applications. ChemPen calculates molecular weight, molecular formula and elemental composition. Watch the animation below or click the drawing to see how easy it was created with ChemPen.

ChemPen+ adds C-13 NMR Shift prediction to ChemPen. If you use C-13 NMR to analyze organic molecules you will appreciate ChemPen+. ChemPen+ uses NMRPenLite©, the same powerful shift prediction module as NMRPen©. NMRPenLite differs from the more powerful NMRPen as follows:

ChemPen+ can estimate the chemical shifts of literally millions of organic compounds. A few examples follow.
