作者在349 GHz频率上寻找了乙炔基CCH的N = 4 - 3转动谱线发射，这些谱线发射指向一些星系分子云。他们已经探测到了10个巨大分子云的辐射，并得出了CCH柱密度在10 14 - 10 15 cm-2的数量级。他们发现CCH发射来自致密气体，n（H2）~ 104 - 105 cm-3，而不是来自非常致密的物质，n（H2）> 106 cm-3，也不是来自热气体，如猎户座的“热核”区域。
The authors have searched for N = 4 - 3 rotational line emission from the ethynyl radical CCH, at 349 GHz toward a number of galactic molecular clouds. They have detected emission from ten giant molecular clouds and have derived CCH column densities on the order of 10 14 - 10 15 cm -2 . They find that CCH emission arises from dense gas, n (H 2 ) ~ 10 4 - 10 5 cm -3 , but not from very dense material, n (H 2 ) > 10 6 cm -3 , nor from hot gas such as the "hot core" region in Orion.
