4D visualization of embryonic, structural crystallization by single-pulse microscopy (2008)
Kwon, Oh-Hoon, Barwick, Brett, Park, Hyun Soon, Baskin, J. Spencer, Zewail, Ahmed H.
Ultrafast vectorial and scalar dynamics of ionic clusters: Azobenzene solvated by oxygen (2006)
Paik, D. Hem, Baskin, J. Spencer, Kim, Nam Joon, Zewail, Ahmed H.
The ultrafast dynamics of clusters of trans-azobenzene anion (A–) solvated by oxygen molecules was investigated using femtosecond time-resolved photoelectron spectroscopy. The time scale for...
Dynamics of clusters: From elementary to biological structures (2006)
Cheng, Po-Yuan, Baskin, J. Spencer, Zewail, Ahmed H.
Between isolated atoms or molecules and bulk materials there lies a class of unique structures, known as clusters, that consist of a few to hundreds of atoms or molecules. Within this range of...
Human myoglobin recognition of oxygen: Dynamics of the energy landscape (2004)
Wang, Yuhong, Baskin, J. Spencer, Xia, Tianbing, Zewail, Ahmed H.
Femtosecond to nanosecond dynamics of O2 rebinding to human WT myoglobin and its mutants, V68F and I107F, have been studied by using transient absorption. The results are compared with NO rebinding....
Zou, Shouzhong, Baskin, J. Spencer, Zewail, Ahmed H.
Molecular recognition by biological macromolecules involves many elementary steps, usually convoluted by diffusion processes. Here we report studies of the dynamics, from the femtosecond to the...
Önfelt, Björn, Lincoln, Per, Nordén, Bengt, Baskin, J. Spencer, Zewail, Ahmed H.
The DNA-intercalating chromophore [Ru(phen)2dppz]2+ has unique photophysical properties, the most striking of which is the "light-switch" characteristic when binding to DNA. As a dimer, it acts as a...
Picosecond real-time studies of mode-specific vibrational predissociation (1990)
Semmes, David H., Baskin, J. Spencer, Zewail, Ahmed H.
The vibrational predissociation of several van der Waals complexes of t-stilbene has been studied by directly measuring, in real time, the fluorescence intensity from the initial reactant state and...
Baskin, J. Spencer, Rose, Todd S., Zewail, Ahmed H.
We present in this Communication preliminary time-resolved fluorescence measurements of supersonaically cooled samples of pDFB and pFT. These measurements indicate that IVR in both cold molecules up...
Baskin, J. Spencer, Felker, Peter M., Zewail, Ahmed H.
In this paper we describe the results of picosecond fluorescence polarization (sub-Doppler) experiments designed to determine the role of purely rotational coherence in two jet-cooled molecules:...
