✦ Synopsis

The rotational spectra of the ground, 18 , 2 18 , and 11 vibrational states of CF 3 CFH 2 have been investigated in the frequency range 48 -116 GHz with an accuracy of measurement better than 10 kHz. Rotational and centrifugal distortion parameters derived using an S-reduced Watson-type Hamiltonian have been improved for the ground and 18 states. An interaction between 2 18 and 11 vibrational states has been detected, and rotational, centrifugal distortion, and coupling parameters of these states have been determined for the first time. The wavenumber difference between the 2 18 and 11 states was found to be 11.20996(54) cm Ϫ1 .
