摘要

使用可调谐二极管激光器测量了 C-H 伸展第一泛音的 C2HD 热带 ro 振荡线的频率。为了将测量范围扩大到大旋转数区域，使用了加热气室。在 R1-R36 和 P2-P14 范围内测量了 (2,0,0,1,0) ← (0,0,0,1,0) 的转变，在 R1-R18 范围内测量了 (2,0,0,0,1) ← (0,0,0,1) 的转变。此外，还确定了(2,0,0,1,0) ← (0,0,0,1,0)带的上下态旋转参数。研究了旋转振荡线的双重结构。对于(2,0,0,1,0) ← (0,0,0,1,0)转变，在 J > 25 时检测到分裂值急剧增加。

High resolution laser diode spectroscopy of the hot bands of C2HD in the first overtone region of C-H stretching

The frequencies of C₂HD hot bands ro-vibrational lines of the first overtone of C-H stretching were measured using tunable diode lasers. To expand the measuring range to the region of the large rotational numbers, a heated gas cell was used. Measurements were made in the range R1–R36 and P2–P14 for the transition (2,0,0,1,0) ← (0,0,0,1,0), and in the range R1–R18 for the transition (2,0,0,0,1) ← (0,0,0,0,1). The rotational parameters of the upper and lower states for the band (2,0,0,1,0) ← (0,0,0,1,0) were determined. The doublet structure of ro-vibrational lines was studied. For the transition (2,0,0,1,0) ← (0,0,0,1,0), a sharp increase in the splitting value was detected at J > 25.
