Absorption spectroscopy of singlet CH(sub 2) near 9500 cm(super -1)

The study stated that the b(super ~) (super 1) B(sub 1) - a(super ~)(super 1)A(sub 1) spectrum of methylene between 9317 and 9610 cm(super -1) were recorded using frequency-modulated diode laser absorption spectroscopy. A comparison of the results of the recent high-level quantum chemical calculations suggested that the further refinement of the potential energy surface of the b(super ~) state near its equilibrium would be done.
