Rotationally resolved Laser-induced Fluorescence measurement is performed on the electronic transition òA' X²E_3/2 of jet-cooled CHD₂O from 2900-3100 cm^-1 in vibrational excitation energy of the òA' 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.
