Experimental confirmation of ground state isotopic isomerization from OCHI to OCID Academic Article uri icon


  • 2014 Elsevier B.V. The 1 spectra of 16O12C-DI and 16O12C-ID, as well as 2 of 16O12C-DI, 16O12C-ID have been recorded using a quantum cascade laser pulsed slit supersonic jet spectrometer. Intensity measurements made simultaneously in the same expansion for transitions in 216O12C-HI: 16O12C-IH and 116O12C-DI: 16O12C-ID isomers permit determination of the isomerization for the former pair to be +2.8(1.0) and the latter -6.0(1.0) cm-1. These results confirm prediction of ground state deuterium isotopic isomerization made using a generated morphed potential. Further analyses indicate OC.HI is a prototype for complexities associated with isomerization and isotopic effects in excited stretching vibrations.
