| Abstract: | The infrared spectra of the isotopic species of HCNH+, HCND+ and H13CNH+, have been observed with a difference frequency laser system. The rs structure of the ion has been determined by combining the rotational constants of the normal species and DCNH+ previously obtained. Two hot bands of the normal species, presumably ν1 + ν4 ← ν4 and ν1 + ν5 ← ν5, have also been observed and the spectroscopic constants have been determined. |
