Abstract

Pure rotational transitions of ⁵²Cr¹⁴N and ⁹⁸Mo¹⁴N radicals in their X ⁴Σ^- state were recorded using a pump/probe microwave-optical double resonance (PPMODR) technique from which the hyperfine parameters of ¹⁴N (I=1) were precisely determined. In addition, the (0,0) A ⁴Π-X⁴Σ band system of ⁵³CrN was recorded from which the hyperfine parameters of ⁵³Cr(I = 3/2) were determined. The newly determined hyperfine interactions for ⁵³Cr and ¹⁴N in CrN and ¹⁴N in MoN and the previously determined hyperfine interactions for other early transition metal mononitrides were analyzed using a simple, single configurational, model. The improved set of fine structure parameters for the CrN and MoN are discussed in terms of possible electronic state distributions.
