Search for methyl carbamate - a glycine isomer - in W51 and TMC-1

The discovery of complex molecules in space has led to the search for amino acids, the pre-biotic molecules, in the ISM. Glycine is one of the simplest amino acids and a privileged ob ject of several detection attempts. However, the search so far has been unsuccessful. A possible explanation is that glycine is not the most stable isomer and probably not the most abundant one. Methyl carbamate, being one of the most energetically stable isomers of glycine as well as having a stronger dipole moment, is the most plausible target for detection in the ISM. We propose to use the Arecibo Observatory to try to detect methyl carbamate towards the HMC W51e2 and the cold region TMC-1. We will thus test two completely different environments for the possible formation of methyl carbamate via different chemical pathways. Although the search for this molecule has been previously carried out at mm-wavelengths, this would be the very first attempt to detect methyl carbamate at cm-wavelengths.
