    Fluorescence depolarisation monitoring of liquid flow before and after exiting a slit nozzle

    Steady-state fluorescence depolarisation was used to study the hydrodynamics of ethylene glycol flow inside a quartz slit nozzle for 24 mm (Re~200) and outside as a free thin jet, for 14 mm. The polarisation prof...

    The influence of hyperfine coherence, elastic and inelastic collisions on state multipoles in laser-excited diatomic molecules

    The observed polarization of single-rotational-level fluorescence in diatomic molecules results from the time evolution of the state multipoles set up in excited molecular arrays. Hyperfine coupling affects th...

    The Influence of Hyperfine Coherence and of Elastic Collisions on the Circular Polarisation of Emission from Li2

    Excitation of an excited state rotational level of a diatomic molecule by circularly polarised light prepares that J′ level with a well defined Mj′ distribution.The excited state ensemble is formed with precis...
