The C${}^1{\Pi }_{\mathrm{u}}$ state of potassium dimer revisited: an~extensive study by polarisation labelling spectroscopy method

W. Jastrzebski, J Szczepkowski, P. Kowalczyk

The polarisation labelling spectroscopy technique was applied to study the C${}^1{\Pi }_{\mathrm{u}}$ $\leftarrow$ X${}^1{\Sigma }_{\mathrm{g}}^{+}$ band system in potassium dimer. About 1100 new r…
