Abstract: Magnetic rotation spectra have been obtained the second overtone (3-0) and a portion of the first overtone (2-0) bands of NO. These spectra are the radiations transmitted through crossed polarizing elements when the radiation traverses the gas paralled to a magnetic field in which in the NO sample is placed. Suitable pressures and absorbing paths were obtained by placing of an air cooled solenoid. Fields of 2400 gauss were used. The magnetic rotation spectrum is quite analogous to the ordinary absorption spectrum. NO deviates from pure case (a) coupling with increasing rotation and as a result the $^{2}\Pi_{1/2}$ state acquires sufficient magnetic characteristics to show a magnetic magnetic rotation spectrum. Rotation spectra are observed for both the $^{2}\Pi_{1/2} - ^{2}\Pi_{1/2}$ and transitions. Observations show that the P Q, and R branches for the $^{2}\Pi{1/2}$ transitions are rotated in a negative sense (counterclockwise looking against the incident light.) The branches for the $^{2}\Pi_{1/2}$ transitions all show a positive rotation.
