Abstract
Progress of spectroscopic studies in soft-X-ray regime is discussed. From the first utilization of ES (Electron Synchrotron) in University of Tokyo, synchrotron radiation spectroscopy, especially in vacuum ultraviolet and soft-X-ray region plays important rolls for the study of condensed matters. Not only the advanced synchrotron light source but also new detection methods have given us a lot of advantages in investigations especially in surface science. Recent trend in spectroscopy is combination with microscopy and time-resolved measurements. These show us the frontiers in intrinsic nature of matters.
