Static gas phase rovibrational analyses have been used to determine the four fundamental stretching band origin frequencies (in cm−1) of 1H13C14N– – –1H19F: ν1=3716.100(3), ν2=3292.1029(3), ν3=2088.9209(7), ν4=167.407(5). Estimated lifetimes in the ν1 and ν3 vibrationally predissociating states are determined to be τ(ν1)=0.052(7) ns; and τ(ν3)=1.1(3) ns, J'≤16; τ(ν3)=0.32(5) ns, J'≥17. The availability of a higher HF rotational energy channel is proposed as a possible mechanism for explaining this sudden change in excited state lifetime.
