Femtosecond photoelectron imaging of pyridazine: S1 lifetime and „3s„nÀ1...,3p„nÀ1...... Rydberg state energetics

چکیده
The first real-time study on pyridazine in the S1(n ,p*) state is presented. The S1 state is found to dephase with a time constant of 323617 ps at its origin, and the electronic dephasing mechanism is attributed to the S1 – S0 internal conversion. The S1 lifetime is found to decrease rather sharply as the internal energy increases. The 3s (n) and 3p (n) Rydberg states of pyridazine are clearly identified in angleand energy-resolved photoelectron images obtained in the (1128) photoionization scheme, providing their respective term values of 5.6860.03 and 6.2860.04 eV. © 2003 American Institute of Physics. @DOI: 10.1063/1.1578062#

The effects of symmetry and rigidity on non-adiabatic dynamics in tertiary amines: a time-resolved photoelectron velocity-map imaging study of the cage-amine ABCO.
The non-adiabatic relaxation dynamics of the tertiary cage-amine azabicyclo[2.2.2]octane (ABCO, also known as quinuclidine) have been investigated following 3p Rydberg excitation at 201 nm using femtosecond time-resolved photoelectron imaging (TRPEI). The aim of the study was to investigate the influence of the rigid and symmetric cage structure found in ABCO on the general non-adiabatic relaxa...
متن کاملUltrafast structural and isomerization dynamics in the Rydberg-exited quadricyclane: norbornadiene system.
The quadricyclane-norbornadiene system is an important model for the isomerization dynamics between highly strained molecules. In a breakthrough observation for a polyatomic molecular system of that complexity, we follow the photoionization from Rydberg states in the time-domain to derive a measure for the time-dependent structural dynamics and the time-evolving structural dispersion even while...
متن کاملPhotoelectron imaging on time-dependent molecular alignment created by a femtosecond laser pulse.
Rotational wave packet revivals on an excited electronic state have been measured by femtosecond time-resolved photoelectron imaging for the first time. The first full revival at 82 ps of S1 (n,pi*) pyrazine was clearly observed in the time dependencies of the photoelectron intensity and the photoelectron angular distribution (PAD). The PAD, measured for laser aligned pyrazine, clearly reflects...
متن کاملNon-Born-Oppenheimer wavepacket dynamics in polyatomic molecules: vibrations at conical intersections in DABCO.
The role of vibrational dynamics in the vicinity of conical intersections is investigated using the first two electronically excited states of 1,4-diazabicyclo[2,2,2]octane (DABCO) by combining time-resolved photoelectron spectroscopy with ab initio computation. Upon resonant excitation of the origin band of the short-lived S2 (1E') state, oscillations in the electronic population between the S...

Time-resolved multiphoton ionization mass spectrometry coupled with Rydberg Fingerprint Spectroscopy (RFS) has been used to analyze the structural and electronic dynamics of N,N-dimethylphenethylamine (PENNA) and N,N-dimethylcyclohexethylamine (CENNA). In PENNA, the molecule converts from 3p to 3s on a time scale of 149 fs, a process that is reflected in the mass spectrum as the onset of fragme...
