Researchers at the Harvard-MIT Center for Ultracold Atoms have recently demonstrated a one-dimensional (1-D) magneto-optical trap (MOT) of polar free radical calcium monohydroxide (CaOH). This technique, outlined in a paper published in Physical Review Letters, was realized by cooling CaOH using radiative laser cooling techniques.
