探索了探测彗星母分子红外分子线辐射的可能性。由于内彗发的非LTE条件和大量的近红外太阳通量，红外荧光将是彗星发射的重要来源，事实上，在足够高分辨率的仪器中，红外荧光将主导谷物辐射。由于地球大气层的吸收，这种线发射的检测将是困难的，但似乎有可能从飞机高度测量彗星的H2O发射。由于红外分子谱线发射是直接探测彗星母体分子的少数几种有前途的方法之一，因此应大力开展对这一问题的进一步研究。
The possibility of detecting IR molecular line emission from cometary parent molecules is explored. Due to the non-LTE conditions in the inner coma and the large amount of near IR solar flux, IR fluorescence will be a significant source of cometary emission and, in fact, will dominate the grain radiation in a sufficiently high resolution instrument. The detection of this line emission will be difficult due to absorption in the terrestrial atmosphere, but it appears possible to measure cometary H2O emission from airplane altitudes. As IR molecular line emission represents one of the few promising methods of detecting cometary parent molecules directly, further research on this problem should be vigorously pursued.
