WebWhy does chloroform have 3 peaks in NMR? Popular Answers (1) It comes from splitting from deuterium. The formula for splitting is 2nI + 1, where n is the number of nuclei, and I is the spin type. Since CDCl3 has 1 deuterium (n = 1), and the spin type is 1 (I = 1), you get 2(1)(1) + 1 = 3, so 3 peaks. Why is CDCl3 used in NMR instead of CHCl3?
