Near-IR distributed feedback semiconductor laser spectroscopy of HCN in natural abundance and in an H(13)CN-enriched sample has been performed from 6380 to 6410 cm(-1). Absolute accuracy of wavenumber measurement was 0.0005 cm(-1) using the 3-0 band of CO as a reference. New sets of molecular constants for the (2 0(0) 0)-(0 0(0) 0) and (2 1(1) 0)-(0 1(1) 0) bands of H(12)C(14)N and H(13)C(14)N have been determined by combining the present results together with the existing data. Two tables of the calculated wavenumbers are given for calibration standards in the 1.5-microm region.
已在6380至6410厘米⁻¹范围内对天然丰度的HCN以及富含H¹³CN的样品进行了近红外分布反馈半导体激光光谱分析。使用CO的3 - 0带作为参考,波数测量的绝对精度为0.0005厘米⁻¹。通过将当前结果与现有数据相结合,确定了H¹²C¹⁴N和H¹³C¹⁴N的(2 0(0) 0)-(0 0(0) 0)和(2 1(1) 0)-(0 1(1) 0)带的新分子常数集。给出了两张计算波数表,用于1.5微米区域的校准标准。
