Ultracold molecules offer unprecedented opportunities for the controlled interrogation of molecular events, including chemical reactivity in the ultimate quantum regime. The proliferation of methods to create, cool, and confine them has allowed the investigation of a diverse array of molecular systems and chemical reactions at temperatures where only a single partial wave contributes. Here we present a brief account of recent progress on the experimental and theoretical fronts on cold and ultracold molecules and the opportunities and challenges they provide for a fundamental understanding of bimolecular chemical reaction dynamics.

“…Molecules in the low velocity tail of such a buffer gas beam can be selected (26,27), trapped (28,29) and cooled (30). Recently, buffer-gascooled beams of a few molecular species have been slowed to low velocity using radiation pressure (31)(32)(33)(34)(35), and CONTACT S.

“…Direct cooling of molecules into the ultracold regime remains elusive, though recent demonstrations of laser cooling show great promise [12][13][14]. An alternative approach is to form ultracold molecules indirectly by association of precooled atoms [15,16].…”

We report the creation of a sample of over 1000 ultracold 87 Rb 133 Cs molecules in the lowest rovibrational ground state, from an atomic mixture of 87 Rb and 133 Cs, by magnetoassociation on an interspecies Feshbach resonance followed by stimulated Raman adiabatic passage (STIRAP). We measure the binding energy of the RbCs molecule to be hc × 3811.576ð1Þ cm −1 and the jv 00 ¼ 0; J 00 ¼ 0i to jv 00 ¼ 0; J 00 ¼ 2i splitting to be h × 2940.09ð6Þ MHz. Stark spectroscopy of the rovibrational ground state yields an electric dipole moment of 1.225(3)(8) D, where the values in parentheses are the statistical and systematic uncertainties, respectively. We can access a space-fixed dipole moment of 0.355(2)(4) D, which is substantially higher than in previous work.
