Abstract

High-resolution spectra of O(17)- and O(18)-enriched water-vapor samples have been recorded with a Fourier transform spectrometer covering the region between 6600 and 7640 cmcm(-1). Experimental values of line positions and strengths of 1807 absorptions in the (120)-(000), (021)-(000), (200)-(000), (101)-(000), (002)-(000), bands of the two isotopic species were derived from the spectra. The analysis included the determination of accurate rotational levels belonging to the (120), (021), (200), (101), and (002) vibrational states of H(2)(17)O and H(2)(18)O.

摘要

使用傅里叶变换光谱仪记录了富含O(17)和O(18)的水蒸气样品的高分辨率光谱，该光谱覆盖了6600至7640 cmcm(-1)之间的区域。从光谱中得出了两种同位素物种在(120)-(000)、(021)-(000)、(200)-(000)、(101)-(000)、(002)-(000)波段中1807条吸收线的位置和强度的实验值。分析包括确定属于H(2)(17)O和H(2)(18)O的(120)、(021)、(200)、(101)和(002)振动态的精确转动能级。
