Fourier-transform spectroscopy and relativistic electronic structure calculation on the $c^3{\Sigma }^{+}$ state of KCs

Artis Kruzins, Valts Krumins, Maris Tamanis +5

The Ti:Saphire laser operated within 13800 - 11800 cm${}^{-1}$ range was used to excite the $c^3{\Sigma }^{+}$ state of KCs molecule directly from the ground $X^1{\Sigma }^{+}$ state. The laser-induced…
