Abstract
We have recently observed transitions to the predissociated, quasilinear $B^{1}A^{\prime}$ state of CHF using a fluorescence dip detected optical-optical double resonance technique.} By exciting selected rovibronic states in intermediate $A^{1}A^{\prime\prime}$ levels belonging to the progressions 2$_0^{n}$, 1$_0^{1}$2$_0^{n}$, and $2_0^{n}3_0^{1}$, a variety of $B^{1}A^{\prime}$ state levels were observed, extending to an energy of 7000 cm$^{-1}$ above the $B^{1}A^{\prime}$ state origin. In this talk, we will focus on the spectroscopy of the $B^{1}A^{\prime}$ state and the excited state barrier to linearity. Experimental data will be compared with $ab$ $initio$ predictions.
