Measurement of the orientation of buffer-gas-cooled, electrostatically-guided ammonia molecules by Heazlewood, B

Measurement of the orientation of buffer-gas-cooled, electrostatically-guided ammonia molecules by Steer, E, Petralia, LS, Western, C, Heazlewood, B, Softley, T

“…The extent to which the spatial orientation of internally and translationally cold ammonia molecules can be controlled as molecules pass out of a quadrupole guide and through different electric field regions is examined. Ammonia molecules are collisionally cooled in a buffer gas cell, and are subsequently guided by a three-bend electrostatic quadrupole into a detection chamber. …”

Electrostatic extraction of buffer-gas-cooled beams for studying ion-molecule chemistry at low temperatures by Twyman, K

“…PGOPHER simulations of the experimental spectra suggest a rotational temperature of 10 K for ND3 molecules (from a 6 K helium buffer gas cell).</p> <p>The extent of translational and rotational cooling can be controlled by varying the molecular and buffer gas densities within the cell, by changing the temperature of the buffer gas cell (we can operate at 6 K or 17 K), or by changing the buffer gas. …”
