Popis:	The $3S\ensuremath{-}5S$ transition of Na atoms is induced by absorption of two photons, one each from two circularly polarized beams traveling in opposite directions through the vapor. The beams are derived from a tunable, narrow-band pulsed dye laser. Doppler broadening is absent and the hyperfine structure is resolved. The hyperfine interaction constant ${A}_{5S}$ in the $5S$ state of the ${\mathrm{Na}}^{23}$ atom is determined to be 101\ifmmode\pm\else\textpm\fi{}15 MHz.
