Control of rotational wave-packet dynamics in asymmetric top molecules
We combine newly developed experimental and theoretical methods to explore and control the rotations of asymmetric top molecules. In the low-temperature limit, the revival spectra of laser-driven rotational wave packets exhibit a fascinating quantum-mechanical structure, which is qualitatively different for asymmetric tops compared to symmetric or linear tops. With increasing fluence, the struc...
متن کاملOriented rotational wave-packet dynamics studies via high harmonic generation.
We produce oriented rotational wave packets in CO and measure their characteristics via high harmonic generation. The wave packet is created using an intense, femtosecond laser pulse and its second harmonic. A delayed 800 nm pulse probes the wave packet, generating even-order high harmonics that arise from the broken symmetry induced by the orientation dynamics. The even-order harmonic radiatio...
متن کاملSpace- and time-resolved measurement of rotational wave packet revivals of linear gas molecules using single-shot supercontinuum spectral interferometry
Femtosecond laser-induced alignment and its periodic quantum revivals are measured in a range of linear gas molecules using an improved version of single-shot supercontinuum spectral interferometry. In particular, room temperature alignment revivals of hydrogen and deuterium molecules are measured for the first time, to the best of our knowledge, in a single shot. Wave packet collisional dephas...
متن کاملImaging the wave functions of adsorbed molecules.
The basis for a quantum-mechanical description of matter is electron wave functions. For atoms and molecules, their spatial distributions and phases are known as orbitals. Although orbitals are very powerful concepts, experimentally only the electron densities and -energy levels are directly observable. Regardless whether orbitals are observed in real space with scanning probe experiments, or i...
متن کاملCoherent imaging of an attosecond electron wave packet.
Electrons detached from atoms or molecules by photoionization carry information about the quantum state from which they originate, as well as the continuum states into which they are released. Generally, the photoelectron momentum distribution is composed of a coherent sum of angular momentum components, each with an amplitude and phase. Here we show, by using photoionization of neon, that a tr...
