✦ Synopsis

The otlcium van der Waals moIcculc, Cal, has been formed by codepositing calcium and krypton atoms on a substrate at 12 K. Absorption spectra revealed a structl;rcd band at 666 nm with 117 ? 2 cm-' spacings. Calcium44 isotopic spcctra confirmed the assignment and located the band origin at 14 432 c 4 cm-*. Emission spectra, pumping the 11 -0 nbsorption, cxhibitcd a very strong 14 000 cm -I band with 78 f 2 cm-' spacings to the band origin and unrelaxed cmisslon wittl78~2ond117-'2cm-~ spacings above the bnnd origin from u' levels up to 6. The transition 'CL ($5 + 'P) + 'XA ('S f 'S) and the bonding in ground and cxcitcd Cs2 states fit u simple molecular orbital modal.

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?
