Reevaluation of C 4 H Abundance Based on the Revised Dipole Moment

Abnormally large column densities of the carbon-chain molecule, C 4 H, have been reported in various sources. The main reason for this was supposed to be an underestimated value of the permanent dipole moment of C 4 H. C 4 H has a low-lying electronic excited state of 2 Π with a large dipole moment...
