Resonantly enhanced twohyphen;photon spectroscopy of HCl and DCl in the 77thinsp;000ndash;87thinsp;000 cmminus;1region

摘要

The twohyphen;photon spectra of HCl and DCl were studied using the technique of resonantly enhanced multiphoton ionization. Rovibrational bands were observed for theXthinsp;1Sgr;+rarr;Vthinsp;1Sgr;+,Ethinsp;1Sgr;+,Fthinsp;1Dgr;2,dthinsp;3Pgr;1,fthinsp;3Dgr;2, andgthinsp;3Sgr;minus;transitions. The results are compared with the single photon spectra of Ginter, Douglas, and cohyphen;workers and with the molecular orbital calculations of Bettendorfetal.
