High-resolution infrared action spectroscopy of the fundamental vibrational band of CN+

Abstract

Rotational-vibrational transitions of the fundamental vibrational modes of the ${}^{12}$C${}^{14}$N${}^{+}$ and ${}^{12}$C${}^{15}$N${}^{+}$ cations have been observed for the first time using a cryogenic ion trap apparatus with an action spectroscopy scheme. The lines P(3) to R(3) of ${}^{12}$C${}^{14}$N${}^{+}$ and R(1) to R(3) of ${}^{12}$C${}^{15}$N${}^{+}$ have been measured, limited by the trap temperature of approximately 4 K and the restricted tuning range of the infrared laser. Spectroscopic parameters are presented for both isotopologues, with band origins at 2000.7587(1) and 1970.321(1) cm${}^{-1}$, respectively, as well as an isotope independent fit combining the new and the literature data.
