We present a theoretical study of the time-dependent laser alignment of molecules taking into account the hyperfine coupling due to nuclear-quadrupole interactions. The coupling of nuclear spins to the overall angular momentum of molecules significantly influences their rotational dynamics. Here, we systematically analyze the impact of the nuclear-quadrupole coupling on the rotational dynamics of the linear I2 and the asymmetric-top diiodobenzene molecule induced by external laser fields. We…

Rotational Coherence Spectroscopy of Molecules in Helium Nanodroplets: Reconciling the Time and the Frequency Domains.
The alignment dynamics calculated from the gas-phase rotational Schrödinger equation, using the experimental in-droplet B and D values, agree in detail with the measurement for all three molecules.
Long-Lasting Orientation of Symmetric-Top Molecules Excited by Two-Color Femtosecond Pulses
Impulsive orientation of symmetric-top molecules excited by two-color femtosecond pulses is considered. In addition to the well-known transient orientation appearing immediately after the pulse and
Femtosecond Rotational Dynamics of D_{2} Molecules in Superfluid Helium Nanodroplets.
Rotational dynamics of D_{2} molecules inside helium nanodroplets is induced by a moderately intense femtosecond pump pulse and measured as a function of time by recording the yield of HeD^{+} ions,


Laser-induced dynamics of molecules with strong nuclear quadrupole coupling.
The method combines the general variational approach TROVE (Theoretical Ro-Vibrational Energies), which provides accurate rovibrational hyperfine energies and wavefunctions for arbitrary molecules, with the variational method RichMol, designed for generalized simulations of the ro vibrational dynamics in the presence of external electric fields.
Hyperfine-Structure-Induced Depolarization of Impulsively Aligned I_{2} Molecules.
A moderately intense 450 fs laser pulse is used to create rotational wave packets in gas phase I_{2} molecules and the ensuing time-dependent alignment exhibits the characteristic revival structures expected for rotational waves but also a complex nonperiodic substructure and decreasing mean alignment not observed before.
Colloquium: Aligning molecules with strong laser pulses
We review the theoretical and experimental status of intense laser alignment---a field at the interface between intense laser physics and chemical dynamics with potential applications ranging from
Time-dependent depolarization of aligned D(2) caused by hyperfine coupling.
Using the hyperfine coupling constants found previously for the ν = 0 state, the time dependence is able to fit essentially within the experimental error, but this requires that the presence of both I(T) = 0 and I( T) = 2 nuclear spin states for this o-deuterium level is properly weighted and taken into account.
Field-free one-dimensional alignment of ethylene molecule
We report an experimental study of nonadiabatic laser-induced molecular alignment of ethylene (C{sub 2}H{sub 4}) using a linearly polarized short laser pulse of moderate intensity. The information
Field-free molecular alignment of asymmetric top molecules using elliptically polarized laser pulses
We show theoretically that a short specific elliptically polarized laser pulse driving an asymmetric top molecule can induce postpulse revivals of three-dimensional (3-D) alignment. By choosing the

A general expression is developed for the time development of the alignment of an ensemble of isolated molecules having two random internal spins when the ensemble is optically pumped by absorption

The creation of alignment by photodissociation is a well‐accepted process. When an isotropic sample of gas is subjected to a strong linearly polarized laser pulse at a frequency at which the

Nonadiabatic alignment of symmetric top molecules induced by a linearly polarized, moderately intense picosecond laser pulse is studied theoretically and experimentally. Our studies are based on the
