The line broadening in the strongest band of NO[sub 2], the [nu][sub 3] band near 1616.85 cm[sup [minus]1], was studied using a spectrometer with pulsed lead salt diode lasers. The examination uses self-broadening experiments as well as broadening with N[sub 2]. He, Ar, and Kr to obtain information on the intermolecular interactions. For a set of quantum numbers with 16 [<=] N[double prime] [<=] 48, 0 [<=] K[double prime][sub a] [<=] 12, the broadening coefficients and spin splittings were determined with an accuracy between 1.5 and 5%. The measured values for the spin splittings are in good agreement with the theoretical values from A. Perrin.
