Ultraviolet emission spectrum of the B(2)Sigma(+) (v = 0)-X(2)Sigma(+) (v = 0) transition of the PN(+) ion has been observed at a resolution of 0.05 cm(-1) by a Fourier transform spectrometer. The rotational analysis led to a great improvement of rotational constants in the B(2)Sigma(+) (v = 0) and X(2)Sigma(+) (v = 0) states as well as to the first determination of centrifugal distortion constants for both levels and spin-rotation interaction constant in the X(2)Sigma(+) (v = 0) state. Rotational perturbation in the B(2)Sigma(+) (v = 0) state was observed. Copyright 2000 Academic Press.
通过傅里叶变换光谱仪以0.05厘米⁻¹的分辨率观测到了PN⁺离子B(2)Σ⁺(v = 0)-X(2)Σ⁺(v = 0)跃迁的紫外发射光谱。转动分析极大地改进了B(2)Σ⁺(v = 0)和X(2)Σ⁺(v = 0)态的转动常数，同时首次测定了这两个能级的离心畸变常数以及X(2)Σ⁺(v = 0)态的自旋-转动相互作用常数。观测到了B(2)Σ⁺(v = 0)态的转动微扰。版权所有2000年，学术出版社。
