The first electronically excited singlet à 1A2 state of formaldehyde (H2CO) is the origin of different competing dissociation channels. An all-ultraviolet (UV) electronically resonant variant of time-resolved fs-two-colour four-wave mixing (fs-TCFWM) spectroscopy has been applied to monitor the dynamics of rovibrational manifolds in this state. The method provides a variety of options to probe molecular dynamics according to the temporal sequence of dipole transitions involved. Signal contributions arising from different molecular states can partially be distinguished by specific sequences of the applied laser pulses. A dispersed signal detection method reveals additional information that is often inaccessible using spectrally integrated detection. We discuss UV-fs-TCFWM experiments which involve resonant transitions to the rovibrational manifolds of the C–O stretch and out-of-plane combination bands in the first electronically excited singlet state of H2CO at energies close to the HCO production threshold. The experimental results are compared to simulations.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
