The A ′( 2 A 1 ′) ← X ( 2 E ′) system of the sodium trimer Na 3 was studied by photodepletion in a supersonic molecular beam, in which the ion signal of Na 3 + generated by one-photon ionization of Na 3 (X 2 E ′ ) with an excimer laser decreased when an excimer-pumped dye laser was also applied prior to the ionizing laser to excite the neutral Na 3 from the X 2 E ′ ground state to the A′ state. Photodepletion spectra were recorded in the wavelength range 700–780 nm with a spectral resolution of 7.5 GHz of the pulsed dye laser. The strongest depletion was found at wavelengths around 740 nm with a measured depletion cross-section of about 1.2 A 2 . Structures with typical widths between 10 and 30 cm −1 were observed in the photodepletion spectra and are attributed to vibronic bands in the A′ state. |
