Photochemical Hole-burning in Photosynthetic Reaction Centers

The change in absorbance (hole spectrum) of the primary electron donor (P870) in bacterial photosynthetic reaction centers has been studied at 1.5-2.1 K following narrow-band excitation at several wavelengths within the P870 absorption band. The hole width is very large, suggesting a homogeneous linewidth on the order of 200-300 cm-‘. Possible interpretations of this highly unusual result, incl...

Photochemical Hole-Burning Spectroscopy of Bovine Rhodopsin and Bacterlorhodopsln

Photochemical hole burning has been observed at 1.5 K in bacteriorhodopsin (bR) and bovine rhodopsin at wavelengths spanning their lowest energy electronic absorption bands. Hole widths were -2500 cm-' full width at half-maximum (fwhm) in bacteriorhodopsin and -2400 cm-' fwhm in rhodopsin. The positions of the hole minima were insensitive to bum wavelength, indicating that minimal site selectio...

Holographic interferometry of ultrafast transients by photochemical hole burning.

A novel approach for interferometric analysis of ultrafast transient processes as short as 10(-13)-10(-14) sec is suggested. The method of holographic storage of ultrafast time-space images in spectrally selective hole-burning materials is used. It is shown that differential interferometric comparison of time-space images, which are permanently stored, provides an effective means to resolve ult...

Response-theory for nonresonant hole burning: Stochastic dynamics

The time signals relevant for nonresonant spectral hole burning, a pump-wait-probe method designed to investigate slow relaxation, are calculated. The step-response function following the application of a high amplitude ac field (pump) and an intermediate waiting period is shown to be the sum of the equilibrium integrated response and a modification due to the preparation via ac irradiation. Bo...

Organizational Black Hole Theory

There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
