spectra of tungsten mononitride WN and rhenium mononitride ReN have been recorded in a laser ablation/molecular beam spectrometer. The field free spectrum of the (0,0)A (4)Pi(3/2)-X (4)Sigma(1/2) (-) band system of (186)WN has been analyzed to produce B("), B('), and gamma(") values of 0.4659(2), 0.4554(2), and 0.0518(1) cm(-1), respectively. The permanent electric dipole moments mu for the X (4)Sigma(1/2)
一氮化钨WN和一氮化meterReN的高分辨率激光诱导荧光光谱已在激光烧蚀/分子束光谱仪中记录。已分析(186)WN的(0,0)A(4)Pi(3/2)-X(4)Sigma(1/2)(-)波段系统的自由场光谱,以产生B(“ ),B(')和gamma(“)值分别为0.4659(2),0.4554(2)和0.0518(1)cm(-1)。X(4)Sigma(1/2)(-)和A(4)Pi(3/2)状态的永久电偶极矩mu分别确定为3.77(18)和2.45(3)D,从光学斯塔克效应的分析。在存在可变静电场的情况下记录了ReN的(0,0)[26.0] 0(+)-X0(+)能带系统。确定(187)ReN的基态和激发态电偶极矩为mu(X0(+))= 1.96(8)D和mu([26.0] 0(+))= 3.53(4)D。分析了无场(187)ReN光谱中的分裂,以产生(187)Re(I = 5/2)核电四极耦合常数e(2)Qq(0)为-0
