Popis:	The infrared absorption spectrum of the ν 4 fundamental band of CH 2 F 2 has been measured in the region 460–600 cm −1 under high resolution. More than 2700 lines have been assigned in this B -type band of the lowest fundamental centered at 528.5 cm −1 . These data have been combined with all available pure rotational measurements on the upper state in a least-squares fit. Accurate values for the band origin and other molecular parameters for the ν 4 state have been obtained which fit the data with an overall standard deviation of 3.7 × 10 −4 cm −1 .
