| 概 要 | Keywords: single molecule spectroscopy, polymers, enzyme, catalysis Over the last 15 years, single molecule spectroscopy (SMS) has been established as a new tool in the ever expanding range of spectroscopic methods. SMS is especially useful to study inhomogeneous systems. Biological systems are by their nature highly heterogeneous and as such perfect targets for SMS. From this it is clear that, next to biological samples, polymers form a study object of SMS as polymers are very often heterogeneous in their behavior. Many theories that describe polymer properties are based on a microscopic picture that now can be evaluated experimentally by applying single molecule techniques. Furthermore, single molecule techniques are very useful for the study of dynamic processes since no synchronization is needed when dynamic events are studied. In this contribution, we will show how different single molecule techniques can be used in the study of dynamic processes at the molecular level. The following topics will be dicussed:
1) Defocused wide-field imaging of moleular rotation in [1-4]
