✦ Synopsis

Infrared-spectra of the isotopic species '3CHSON0, CH,'*ONO, CH,O"NO and CHjON'*O, isolated in argon matrices, are reported. Spectral data together with earlier data on CHrONO are used for derivation of 22 parameter harmonic valence force fields for both the cis and trans conformers and assignments are presented for all isotopic species in the two conformations. The valence force field will be used to propose assignments of cis and trnns C40NO reported earlier by OGILVIE.

A comparison of force constants of molecules with C-O, N-O, and N=O fragments and their dependence on conformation and structure is made.

The inverse spectral problem for porphin is solved by the regularized least squares method. For determining 30 force constants related to in-plane molecular vibrations, 256 frequencies of porphin and its four deuteratcd derivatives are used. The form of the porphin molecule vibrations is discussed.
