have been observed with ≈1 cm −1 and ≈2.5 cm −1 resolution, respectively. Molecular constants were calculated from the observed frequencies. Within the accuracy of measurement the observed constants agree with those previously reported ( 1 ) for hydrogen fluoride ( g ). The “least squares” values of the molecular constants in cm −1 are: ν 1←0 = 2443.86, ν 2←0 = 4823.8, ω e = 2508.5, x e ω e = 32.5, B e
摘要
氟化氚( g ) 的ν 1←0 和ν 2←0 振动-旋转线已经分别以≈1 cm -1 和≈2.5 cm -1 的分辨率被观测到。从观察到的频率计算分子常数。在测量的准确度内,观察到的常数与先前报道的
氟化氢 (g) 的常数 (1) 一致。以 cm -1 为单位的分子常数的“最小二乘”值是: ν 1←0 = 2443.86, ν 2←0 = 4823.8, ω e = 2508.5, xe ω e = 32.5, B e = 7.69, α e = 0.176 , De = 2.5 × 10 -4 。键距为 0.917 A,力常数为 9.65 × 10 5 达因/厘米。
