351 optogalvanic transitions have been observed in the 337-598 nm wave
length region using an iron-neon hollow cathode discharge lamp and a p
ulsed tunable dye laser. 223 of these have been identified as transiti
ons associated with neon energy levels. These optogalvanic transitions
have allowed, in conjunction with interference fringes recorded conco
mitantly with an etalon, the calibration of the dye laser wavelength w
ith 0.3 cm(-1) accuracy.
