Quantum chemical rovibrational spectroscopic data for possible observation of thiocarbonic acid (H2CS3) in interstellar environments.

The second-lowest conformer of thiocarbonic acid (cis-trans-H2CS3) lies 0.64 kcal mol-1 above the global minimum and possesses a 2.17 D dipole moment compared to the 0.75 D dipole moment of the cis-cis global minimum. While these properties are quali…
