Diode laser spectroscopy of the ν4 (HCN bend) band of HCNH +
Abstract
The ν4 (HCN bend) band of the HCNH + ion has been observed by diode laser spectroscopy using a magnetic field modulation technique. Twenty-three Q-, P-, and R-branch lines were observed and analyzed to yield the rotational, centrifugal distortion, and l-type doubling constants for the ν4 state. The band origin was determined to be 801.5934(6) cm -1.
