Exotic Molecules in Space: A Coordinated Astronomical, Laboratory, and Theoretical Study

Great strides been made during the past three years in our laboratory investigation of molecules of astrophysical interest. Between 20 and 30 new molecules have been discovered each year of the grant with our ultrasensitive Fourier-transform microwave (FTM) spectrometer, bringing the total found during the last three years to 83. Six of these have already been discovered by us and colleagues in at least one astronomical source in the Galaxy, and a seventh, the molecular ion HC3NH+, has been detected by a Japanese group at Nobeyama Observatory. It is likely that most or many of the remaining 76 will be found with the powerful radio and far infrared telescopes now under construction or planned. The 32 papers published or submitted during the grant period are listed.
