High-resolution spectroscopy of HCl and DCl isolated in solid parahydrogen: Direct, induced, and cooperative infrared transitions in a molecular quantum solid

摘要: The infrared spectroscopy and rovibrational dynamics of HCl DCl dopants in solid parahydrogen (pH2) were investigated using high-resolution spectroscopic methods. absorption spectra monomers pH2 closely resemble the corresponding low temperature gas phase spectra, indicating that vibrational rotational quantum numbers dopant are conserved within solid. Small deviations from behavior observed, however, such as a reduced energy level spacing splitting fivefold orientational degeneracy states with J=2. In addition, pure Q1(0) (v=1←0, J=0←0) H2 transition, which is inactive pH2, detected doped sample. We propose this transition induced molecules by neighboring through weak “overlap induction” mechanism only induction operative for J=0 impurities pH2. Rovibrational transitions a...
