X ̃ 1 Σ g+ ground state. The inherent nonlinear signal dependence and coherence of the
technique result in a favorable detection of the excited triplet states of interest. The …

Developments in experimental and theoretical methods are continually shedding new light
on molecule-surface scattering. Utilizing the two approaches in a complimentary fashion, the …

The dynamics of proton transfer in the first excited singlet state of malonaldehyde [Ã 1 B 1
(π* n)] have been investigated through the use of high-resolution degenerate four-wave …

Two-color resonant four-wave mixing (TC-RFWM) spectroscopy has been used to probe
highly excited v= 0 and v= 1 Rydberg states of nitric oxide. Transitions to n= 16–30, v= 0 …

We present a combined theoretical and experimental study of the effects of laser polarization
on optical coherences produced in two-color, resonant four-wave mixing (TC-RFWM). A time …

The ns, np and nf high Rydberg series of NO below the ionization limit are studied by two-
color resonant four-wave mixing spectroscopy. The Rydberg states are prepared by two-step …

Amplified spontaneous emission ASE from single rotational levels of Rydberg states, 4p M 2,
4p K 2, 5s S 2, 4d O 2, 4d O 2, 5p R 2, and 5p Q 2 of NO molecules has been investigated …

Diagrammatic perturbation theory and the spherical tensor formalism are used to model the
signal observed in time-resolved, two-colour resonant four-wave mixing (TC-RFWM). An …

Spectra of the B3Π0+ u− X1Σg+ system of gaseous Br2 with stimulated-emission pumping in
the static gas cell and in a jet were measured via two-colour resonant four-wave mixing …

A treatment of continuum states in the application of diagrammatic perturbation theory to
calculate the signal produced in two-color resonant, four-wave mixing (TC-RFWM) …
