Observation of strong nonlinearities in the high field Zeeman spectrum of NO at 1876 cm−1

Abstract
Strong nonlinearities have been observed in the Zeeman effect in NO and quantitatively explained by taking account of off‐diagonal Zeeman interaction terms in an accurate Hamiltonian diagonalization calculation. Zeeman spectra were obtained by tuning the Q(3/2)3/2 and Q(5/2)3/2 transitions of the fundamental band (1876 cm−1) through the P(15)9,8 laser line of CO.
