Interstellar Methoxy Clause Samples

Interstellar Methoxy. The CSO observations offer a large dataset with which laboratory spectra can be compared. There is much interest in the interstellar detection of methoxy and other organic species that are intermediates during the formation/destruction of more complex species. Such obser- vations provide tight constraints that may be tested against current astrochemical models, as well as helping guide future ones. Methoxy has recently been identified in the ISM, toward the dense, cold core B1-b via emission lines at wavelengths near 2 mm and 3 mm (Cernicharo et al., 2012). Relative intensities of the hyperfine components of the emission lines suggested a rotational tem- perature of 10 ± 3 K. At these temperatures, the rotational lines at higher frequencies, near
