Abstract : The sodium D2 line Doppler profile was measured from observed fluorescence of the electronically excited sodium atom generated by photodissociation of NaI by ultraviolet wavelength light in the 2100-2500A region. The experimentally determined Doppler profile is compared to an ideal Doppler profile calculated by considering the vibrational and rotational states of the NaI molecule and by considering the excited sodium atom recoil velocities and the most probable NaI thermal speeds. Effect of polarization of the exciting ultraviolet on the angular velocity distribution of the dissociation products of NaI was measured.
