Over many millennia, humankind has thought to explore phenomena on an ever shorter time
scale. In this race against time, femtosecond resolution (1 fs= 10− 15 s) is the ultimate …

Ultrafast energy transfer is used to transmit electronic excitation among the many molecules
in photosynthetic antenna complexes. Recent experiments and theories have highlighted …

This anthology, which is adapted from the Nobel Lecture, gives an overview of the field of
Femtochemistry from a personal perspective, encompassing our research at Caltech and …

The genesis of the exploration of electron transfer (ET) in the condensed phase dates back
to the origins of chemistry in the nineteenth century. In 1808 Humphry Davy observed [1] that …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

1. General Aspects 2. Normal-Mode Taylor Expansion 3. A Model of Nonadiabatic
Photoisomerization III. Time-Dependent Methodology A. Representation of the State Vector …

We analyze the spectral changes that occur when unfocused intense femtosecond pulses at
800 nm propagate through different atomic and molecular gases. The observed red shift in …

Two coherent frequency combs are used to measure the full complex response of a sample
in a configuration analogous to a dispersive Fourier transform spectrometer, infrared time …

▪ Abstract There has been much progress in the control of chemical reactions since methods
of active control were first proposed by Brumer & Shapiro and by Tannor & Rice ten years …

Calculations are presented of vibrational wave packet dynamics in H 2+ ions formed by
ionization of neutral H 2 by a pair of attosecond extreme ultraviolet laser pulses, using time …
