Optically active molecular materials, such as organic conjugated polymers and biological
systems, are characterized by strong coupling between electronic and vibrational degrees of …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

MOLCAS/OpenMolcas is an ab initio electronic structure program providing a large set of
computational methods from Hartree–Fock and density functional theory to various …

Multichromophoric biosystems represent a broad family with very diverse members, ranging
from light-harvesting pigment–protein complexes to nucleic acids. The former are designed …

Computational spectroscopy is becoming a mandatory tool for the interpretation of the
complex, and often congested, spectral maps delivered by modern non-linear multi-pulse …

We report O–H----S hydrogen-bond (H-bond) formation and its excited-state intramolecular
H-bond on/off reaction unveiled by room-temperature phosphorescence (RTP). In this …

Heavy-atom-free photosensitizers (HAF-PSs) based on thionation of carbonyl groups of
readily accessible organic compounds are rapidly emerging as a versatile class of …

The conversion of photon energy into other energetic forms in molecules is accompanied by
charge moving on ultrafast timescales. We directly observe the charge motion at a specific …

We report on the complete temporal characterization of ultrashort pulses, generated by
resonant dispersive wave emission in gas-filled hollow-capillary fibers, with energy in the …

Mercury is a contaminant of global concern that is transported throughout the atmosphere as
elemental mercury Hg0 and its oxidized forms HgI and HgII. The efficient gas‐phase …
