Abstract
The gaseous infrared spectra of CH2N2, CHDN2, CD2N2, and CH2N15N have been examined between 230 and 4000 cm—1 under medium resolution. Band positions have been measured for all the distinguishable parallel features. Nearly all of the perpendicular fundamentals have been resolved and analyzed. The [A″—½(B″+C″)] rotational constants derived are: CH2N15N, 8.747±0.015 cm—1; CD2N2, 4.253±0.01 cm—1; CHDN2, 5.72±0.1 cm—1. These data combined with that given earlier for the CH2N2 isotope, show that the averaged distance of the hydrogen atoms from the molecular axis (in CH2N2 and in CH2N15N) is 0.9580±0.0006 Å and of the deuterium atoms (in CD2N2) is 0.9560±0.001 Å. In contrast to earlier studies, we were able to find no evidence for the presence of a tautomeric form of diazomethane in the samples studied.Keywords
