NO分子线强与带强的近似计算

APPROXIMATE COMPUTATIONS FOR THE INTENSITIES OF LINES AND BANDS OF NO MOLECULE

从描述ＮＯ分子振转光谱线强的复杂表达式出发，利用适当的近似，导出了ＮＯ分子线强与５．３μｍ和２．７μｍ带强的解析式，并将计算结果与ＨＩＴＲＡＮ光谱线强和有关文献的测量结果作了比较。

onvenient analytical formulas for the intensities of individual lines and bands of 5.3μm and 2.7μm of NO are derived by starting from the complex expression of its vibration-rotation spectral line intensities, and using suitable approximations. The results of the calculation are compared with the HITRAN spectral line intensities and the results of the measurements in related literature, it is shown that approximate analytical formulas derived from this paper are reasonable accurate, and their relative errors are less than 2%.
