The dynamics of the ferric CN complexes of the heme proteins Myoglobin and Hb I from the clam Lucina pectinata upon Soret band excitation is monitored using IR and broad band visible pump-probe...
Ramos, Cacimar, Ramirez, Eunice, Ruiz, Carlos, Pietri, Ruth, Lopez Garriga, Juan, Helbing, Jan, ...
Hb I (HbI) is an invertebrate monomeric hemeprotein from Lucina pectinata that contains 142 amino acid residues. The HbI heme pocket structural compn. shows an arrangement of phenylalanyl residues...
Solvation of ion-pair states in nonpolar media: I2 in solid neon, argon and krypton (2001)
The ion-pair state emission spectra of I2 isolated in Ne, Ar, and Kr matrixes at 300-700 nm and vacuum UV spectra at 50,000-60,000 cm-1 are presented. Spectroscopic anal. of the UV and visible...

Caging and excited state emission of ICN trapped in cryogenic matrixes: experiment and theory (2000)
Helbing, Jan, Chergui, Majed, Fernandez-Alberti, Sebastian, Echave, Julian, Halberstadt, Nadine, Alberto Beswick, J.
The cage-induced stabilization of fragments in excited electronic states following the UV-dissocn. of ICN in cryogenic matrixes is discussed. Emission spectra recorded upon ~A-band excitation of ICN...
Picosecond conformational transition and equilibration of a cyclic peptide
Bredenbeck, Jens, Helbing, Jan, Sieg, Arne, Schrader, Tobias, Zinth, Wolfgang, Renner, Christian, ...
Ultrafast IR spectroscopy is used to monitor the nonequilibrium backbone dynamics of a cyclic peptide in the amide I vibrational range with picosecond time resolution. A conformational change is...

Folding and unfolding of a photoswitchable peptide from picoseconds to microseconds
Ihalainen, Janne A., Bredenbeck, Jens, Pfister, Rolf, Helbing, Jan, Chi, Lei, ...
Using time-resolved IR spectroscopy, we monitored the kinetics of folding and unfolding processes of a photoswitchable 16-residue alanine-based α-helical peptide on a timescale from few picoseconds...
Protein ligand migration mapped by nonequilibrium 2D-IR exchange spectroscopy
Bredenbeck, Jens, Helbing, Jan, Nienhaus, Karin, Nienhaus, G. Ulrich, Hamm, Peter
2D-IR exchange spectroscopy has been introduced recently to map chemical exchange networks in equilibrium with subpicosecond time resolution. Here, we demonstrate the generalization of 2D-IR exchange...
