The microwave absorption spectrum of methyl alcohol was studied in the region 23,400 to 25,200 Mc., using a double modulation system in which the usual radio-frequency sine wave was replaced by a sharp, pip-shaped pulse with a repetition rate of 55 kc. Twenty-five new lines were found and these, along with those previously reported outside the region examined, were grouped into four series. When the methyl alcohol was mixed with a large percentage of water vapor the spectrum was found to be modified considerably.


The infra-red absorption spectrum of nitrosyl chloride was investigated with two objects in view. Firstly, if the substance is a covalent compound with normal valency linkings, the molecule will probably be asymmetrical and triangular. If this is so, the absorption bands will show no pronounced branch maxima such as are predicted and observed for symmetrical molecules, and the presence or absence of these maxima in the same conditions of resolution and concentration provides a test of the theory according to which the spectra of such gases as SO 2 , ClO 2 , and Cl 2 O have been interpreted. The two former molecules are required by the theory to be symmetrical, although such symmetry is not to be expected from the ordinary rules of valence. The experimental fact that the characteristic P, Q, and R branch maxima are absent in NOCl thus provides a verification of the theory. Secondly, six electrons are effectively available for binding in the molecule, and accordingly the structure should be triangular with a vertical angle ONCl approximately 120°, and governed by a valence force system. The molecule should, therefore, show whether or not the structure of triatomics is determined primarily by the number of available binding electrons.
