Abstract
We report a comprehensive list of accurate Ritz wavelengths and calculated transition probabilities for parity-forbidden [Mn II] lines along with new calculations for their associated transition probabilities. Ritz wavelengths have been derived from experimentally-established energy level values resulting from an extensive analysis of a high-resolution Fourier transform emission spectrum of singly-ionized manganese. Our analysis includes transitions between all known metastable and other long-lived levels of Mn II giving a total of 1130 [Mn II] Ritz wavelengths. Our entire list of derived Ritz wavelengths for [Mn II] lines range between 237 nm and 170 m (42125 cm..1 to 58 cm..1).
