摘要: Several molecular clouds have been searched for absorption at 7.6 microns due to gaseous and solid methane. Gaseous CH4 was detected toward NGC 7538 IRS 9 probably OMC-1 IRc2 W33 A. The abundance of is typically 0.001 that CO. Solid possibly A 1. comparable total (predominantly in the phase) 1-4 percent CO gaseous). high fraction state suggests it made grain mantles. 22 refs.
