| Abstract: | Three-dimensional orientation is one important dynamic properties of single molecules. Three- dimensional orientation of single molecules is one of hotspots in research of single molecules. Three schemes for determination of the three-dimensional orientation of single molecules are summarized. Their principles are introduced. Their advantages and disadvantages are analyzed. The difficulties and pratical issues in the measurements are discussed, and the application prospect are introduced. |
