Rotational spectrum of vinyl formate (CH_2_=CHOCHO)
Listed in IVOA Registry (Virtual Observatory)
Previous detections of methyl and ethyl formate make other small substituted formates potential candidates for observation in the interstellar medium.
Description
Among them, vinyl formate is one of the simplest unsaturated carboxylic ester. The aim of this work is to provide direct experimental frequencies of the ground vibrational state of vinyl formate in a large spectral range for astrophysical use.
The room-temperature rotational spectrum of vinyl formate has been measured from 80 to 360GHz and analyzed in terms of Watson's semirigid rotor Hamiltonian. Two thousand six hundred transitions within J=3-88 and K_a_=0-28 were assigned to the most stable conformer of vinyl formate and a new set of spectroscopic constants was accurately determined. Spectral features of vinyl formate were then searched for in Orion KL, Sgr B2(N), B1-b, and TMC-1 molecular clouds.
