โฆ Synopsis
An infrared matrix isolation study has been performed for sodium and benzene mixtures in solid argon at 9 K. In contrast with the earlier report, sodium was evidenced to form complexes with benzene. Although the exact nature of the complexes is not certain, ab initio quantum mechanical calculation indicated clearly that the 1 : 1 Na-C6H 6 complex should be as stable as the 1 : 1 Li-C6H 6 complex. The tentatively assigned peak frequencies for the 1 : 1 Na-C6H 6 complex were also in fair agreement with the theoretical values.

Diatomic fluorine was reacted in a low pressure flame with selenium atoms, generated by a microwave discharge in argon seeded with Se 2, and the products were trapped in solid argon; new infrared absorptions were found at 677.0 and 680.4 cm-l for 8ยฐSe19F and 76selgF, respectively.
Calcium atoms have been reacted with NO and NO2 upon condensation at high dilution in argon at 15 K. Infrared absorptions at 1357 and 455 cm-\* show appropriate isotopic shifts to be due to @I -O)-and Caf -(NO)-viirations in the Ca%O-species. A strong band at 1244 cm-l is due to YJ of NO; in the Ca?
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 geometr
