✦ Synopsis

The observation of new fundamental frequencies for the potassium superoxide KO1 is reported for different isotopic species: v3 of 39K'602, 39K's02 and 39K'60'80, and v2 of 4*K'602, 41K'*02, 4'K'601s0 and 39K'70180. Using these values and a fixed O-0 internuclear distance, we calculated the geometry and force constants from a harmonic force field. We estimated an O-K-O angle of 37" + 2", and a K-O internuclear distance of the order of 2.10 + 0.14 A. These values disagree with previous theoretical determinations.

## Abstract The far infrared spectra of poly(L‐proline) I (190–35 cm^−1^) and II (400–35 cm^−1^) were obtained in the solid state at both 300° and 110°K. A significant difference in the region below 100 cm^−1^ was observed. A very intense band located at 60 cm^−1^ in the infrared spectrum of form I
