Dynamics in low temperature glasses: Theory and experiments on optical dephasing, spectral diffusion, and hydrogen tunneling
TL;DR: In this article, temperature dependent photon echo (PE) and nonphotochemical hole burning (NPHB) measurements were reported on resorufin in three organic glasses: ethanol (1.5 −11 K), glycerol (1 −1 −25 K), and d−ethanol (1−1−11 K).

Measurement of Local DNA Reorganization on the Picosecond and Nanosecond Time Scales
TL;DR: Picosecond and nanosecond dynamics in the interior of DNA are observed for the first time as a dynamic Stokes shift in the fluorescence of a specially designed base-pair analogue.

LIBS using dual- and ultra-short laser pulses
TL;DR: A simple near-collinear dual-pulse fiber-optic LIBS probe is shown to be useful for enhanced LIBS measurements and non-gated detection of LIBS is shows to be very effective.

Studies of chemical reactivity in the condensed phase. I. The dynamics of iodine photodissociation and recombination on a picosecond time scale and comparison to theories for chemical reactions in solution
TL;DR: In this article, a detailed model of the reaction of geminate recombination and vibrational relaxation is presented, which resolves disagreements over the time scales of the recombination process and the role of excited electronic state trapping.

Complex Local Dynamics in DNA on the Picosecond and Nanosecond Time Scales
TL;DR: Time-resolved Stokes shift measurements of the local structural relaxation of three DNA oligonucleotides are presented, indicating a complex relaxation among a large number of conformational substates and infer that 30%-50% of the relaxation is faster than 40 ps, has a nonlogarithmic decay and has a sequence dependent amplitude.
