Abstract

The energies, widths and absolute intensities of the P(1) v'' = 0, J'' = 1 absorption transitions of H(2) have been measured in the spectral range of 81-75 nm using monochromatized synchrotron radiation. This work completes and extends previous observations, in particular those of Herzberg and Jungen [J. Mol. Spectrosc. 41, 425 (1972)]. Ab initio multichannel quantum defect theory (MQDT) is used to corroborate the spectral analysis of the experimental data. Line intensities and decay widths are also calculated using MQDT.

摘要

使用单色同步加速器辐射，在 81-75nm 的光谱范围内测量了 H(2)的 P(1) v''=0,J''=1 吸收跃迁的能量、宽度和绝对强度。这项工作完成并扩展了先前的观察结果，特别是 Herzberg 和 Jungen 的观察结果[J. Mol. Spectrosc. 41, 425 (1972)]。使用多通道量子数亏损理论（MQDT）来证实实验数据的光谱分析。还使用 MQDT 计算了线强度和衰减宽度。
