摘要
在１７０７９～１７４０７ｃｍ－１范围内，利用了塞曼调制磁旋转光谱技术测量了Ｎ２分子第一正带Ｂ３∏ｇ～Ａ３∑＋ｕ的（１０，６）、（１１，７）、（１２，８）带的近９００条谱线，其中包括了用以往各种光谱技术很难观测到的Ｐ１３、Ｑ１３、Ｒ１３和Ｐ３１、Ｑ３１、Ｒ３１支线，给出了量子态的标识，并且拟合出相应的转动分子常数。
The (10,6),(11,7),(12,8)bands of the first positive band B 3∏ g～A 3∑ + u of N 2 are analyzed via Zeeman-modulation Magnetic-Rotation Spestroscopy in the range of 17079～17407cm -1 .Near 900 spectral lines are labeled,including P 13 、Q 13 、R 13 and P 31 、Q 31 、R 31 branches which have scarcely been observed before,and the improved molecular rotation constants for v=6,7,8 levels of A state and for the v=10,11,12 levels of B state have been obtained by the means of the nonlinear least squares fitting.
