摘要: We have identified vibrationally excited CH3CH2CN (ethyl cyanide) for the first time in interstellar medium. Using Caltech Submillimeter Observatory, Berkeley-Illinois-Maryland Association Array, and Millimeter we detected several transitions from both vb = 1 in-plane bending state vt torsional Sgr B2(N-LMH) source. Because these states lie near 300 K above ground, is potentially a useful probe of hottest regions dense, dusty molecular cloud cores where massive star formation occurring. In addition, this identification will help account many unidentified misidentified spectral lines observed hot cores.
