The photoelectron spectrum of iminoacetonitrile (HN=CHCN), obtained by gentle pyrolysis of the sodium salt of 1-cyanoformamide tosylhydrazone at 200-degrees-C, is reported. The first (vertical) ionization potentials are 11.60, 12.34, 13.09, 13.84, and 14.51 eV. These are compared with those of N-cyanomethanimine (CH2=N-CN).
