Einstein coefficients and transition moment variation for the NO(A 2Σ+–X 2Π) transition

Branching ratio measurements for the NO γ bands excited by energy transfer from metastable nitrogen molecules show that the electronic transition moment for the NO(A 2Σ+–X 2Π) transition varies by about 40% over the r-centroid range of 1.13–0.97 Å. Combining this transition-moment variation with radiative lifetime measurements provides a complete set of Einstein coefficients for NO(A–X) transitions from v′=0–2.
