A vibrational-rotational spectrum of the deltanu=2 transitions of a high-temperature molecule AlF was observed between 1,490 and 1,586 cm(-1) with a diode laser spectrometer. Measurements were made on the nu=3-1, 4-2, 5-3 and 8-6 bands at a temperature of 900 degrees C. Measured spectral lines were fitted to effective band constants nu(0), B(nu) and D(nu) for each band. Present measurements were made with only one Pb-salt laser diode. Physical significance of the effective band constants is discussed.
利用二极管激光光谱仪在1490至1586厘米⁻¹之间观测到了高温分子AlF的Δν = 2跃迁的振动 - 转动光谱。在900摄氏度的温度下对ν = 3 - 1、4 - 2、5 - 3和8 - 6带进行了测量。将测量得到的谱线拟合到每个带的有效带常数ν(0)、B(ν)和D(ν)上。本次测量仅使用了一个铅盐激光二极管。讨论了有效带常数的物理意义。
