The interstellar chemistry of C3H and C3H2 isomers [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We report the detection of linear and cyclic isomers of C3H and C3H2 towards various starless cores and review the corresponding chemical pathways involving neutral (C3Hx with x=1,2) and ionic (C3Hx+ with x = 1,2,3) isomers.

Bonding and correlation analysis of various SiCO isomers
, 2002 The structural properties for various SiCO isomers in the singlet and triplet states have been investigated using CASSCF methods with a 6-311 +G* basis set and also using three DFT and MP2 with same basis set for those systems except for the linear ...
