Detection of the 13C isotope formamide in the galactic center.
Abstract
. We have observed the i - i F = 2 - 2 line of normal and 13C substituted formamide (NH2 CHO) in the direction of Sgr B2. We find that both lines are optically thin and that the ratio of column densities is 24 + 6 (2 Key Words. lecules, Abundances, Isotopes.
