RESONANT TWO-PHOTON IONIZATION SPECTROSCOPY OF JET-COOLED OSMIUM NITRIDE

Author Institution: Department of Chemistry, University of Utah, Salt Lake City, Utah, 84112Optical transitions of supersonically cooled OsN were investigated for the first time in the range between $19,231$ and $22,988$ $cm^{-1}$ by resonant two-photon ionization technique. Ten bands were rotationally resolved for the four largest isotopomers, $^{192}Os^{14}N$ $\left(40.78\%\right)$, $^{190}Os^{14}N$ $\left(26.26\%\right)$, $^{189}Os^{14}N$ $\left(16.12\%\right)$ and $^{188}Os^{14}N$ $\left(13.24\%\right)$
