The rotational spectrum of fluoroiodomethane, CH2FI, has been recorded in the 1.02–1.05 THz frequency range, allowing us to extend the set of known spectroscopic parameters with respect to our previous work. In particular, three additional octic centrifugal-distortion constants and the K-dependence for all quadrupole-coupling constants have been determined. Furthermore, the rotational spectrum of the v6 = 1 vibrational state has been recorded and assigned in the 171–184 and 534–536 GHz frequency ranges, spanning the quantum number J from 4 to 79. This allowed us to provide for the first time accurate rotational, quartic, sextic, and three octic centrifugal-distortion constants and the iodine hyperfine parameters.

Abstract
The rotational spectrum of fluoroiodomethane, CH2FI, has been recorded in the 1.02–1.05 THz frequency range, allowing us to extend the set of known spectroscopic parameters with respect to our previous work. In particular, three additional octic centrifugal-distortion constants and the K-dependence for all quadrupole-coupling constants have been determined. Furthermore, the rotational spectrum of the v6 = 1 vibrational state has been recorded and assigned in the 171–184 and 534–536 GHz frequency ranges, spanning the quantum number J from 4 to 79. This allowed us to provide for the first time accurate rotational, quartic, sextic, and three octic centrifugal-distortion constants and the iodine hyperfine parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
