Rotationally resolved Laser-induced Fluorescence measurement is performed on the electronic transition $A~2A\prime \leftarrow X~2E3/2$ of jet-cooled $CHD2O$ from $2900-3100cm-1$ in vibrational excitation energy of the $A~2A\prime$ state, where ab initio result suggests the fundamental of C-H stretch is located. Resorting to a rotational analysis, eight vibrational bands are recognized and characterized. The vibrational assignments are confirmed by a relative intensity analysis and the symmetries thoughtfully determined in the rotational analysis.
