Abstract

The A′(²A₁′)←X(²E′) system of the sodium trimer Na₃ was studied by photodepletion in a supersonic molecular beam, in which the ion signal of Na₃⁺ generated by one-photon ionization of Na₃ (X²E′) with an excimer laser decreased when an excimer-pumped dye laser was also applied prior to the ionizing laser to excite the neutral Na₃ from the X²E′ 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 Å². 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.
