Rotational Correlation Functions of Single Molecules

Time Correlation Functions for Internal and Anisotropic Rotational Motion of Molecules

By use of Green 's functions f o r the diffusional motion a very concise formulation and computation of correlation functions is possible. For an axially symmetric overall diffusion with internal rotation about one and two axes correlation functions of a second rank spherical tensor are calculated. The results comprise all the solutions of the pertinent problem as given so far and allow the ext...

Rotational motions of macro-molecules by single-molecule fluorescence microscopy.

Several complementary techniques have been developed to determine average orientation, dynamics on multiple time scales, and concerted rotational motions of individual fluorescent probes bound to biological macromolecules. In both protein domains and nucleic acids, tilting and wobble are relevant to their functional mechanisms. Here we briefly review methods to detect angles and rotational moti...

Orchestration of Single Molecules for Novel Functions

A01 Prof. Ogawa’s group Synthesis and measurements of molecular composites bearing non-symmetric and/or non-linear single molecule electronic properties We are synthesizing new molecules which possibly have non-linear and non-symmetric single molecule electric properties such as rectification, negative differential resistance, and hysteresis. The measurements are performed by a PCI-AFM techniqu...

Rotational Spectroscopy of Diatomic Molecules

Single-site- and single-atom-resolved measurement of correlation functions

Correlation functions play an important role for the theoretical and experimental characterization of many-body systems. In solid-state systems, they are usually determined through scattering experiments whereas in cold-gases systems, time-of-flight and insitu absorption imaging are the standard observation techniques. However, none of these methods allow the in-situ detection of spatially reso...
