AbstractInfrared spectra of isotopically substituted HeN-CO clusters (1<N<19) have been studied in order to extend the original results on the normal isotope [J. Tang and A. R. W. McKellar, J. Chem. Phys. 119, 754 (2003)]. The same two series of R(0) transitions were observed, correlating with the a- and b-type transitions of He1-CO, with only small shifts in relative position. The previously obscured a-type line for He6-CO was detected. Examination of the small shifts among isotopomers showed remarkably smooth behavior, except in the "unstable" regions around N = 7 (b-type series) and 15 (a-type series). The overall results firmly support the assignments and analysis given for the normal isotope.
