“…Biomolecules in particular could reveal their true nature in an aqueous environment. Additionally, heterogeneous catalytic reactions at the solid–liquid interface can be investigated in a new way to gain a deeper insight into electrochemical processes. ,,, Second, the heat from the laser source required for Raman spectroscopy is dissipated much better in water than in air . This reduces the degradation of heat-sensitive analytic compounds.…”

Tip-enhanced Raman spectroscopy (TERS) is an emerging technique with a large number of potential applications in different fields such as chemistry, physics, biology, life sciences, and materials science. TERS in liquids offers nondestructive and label-free topographical and chemical imaging of molecules and chemical reactions under native conditions at a nanometer scale. It combines Raman spectroscopy with scanning probe microscopy, providing a unique combination of chemical information and high spatial resolution. The versatility of TERS increases even further if it is modified for simultaneous electrochemical measurements. This paper reviews the recent progress of TERS in liquid, with a focus on molecular structures, interfaces, and chemical reactions studied to date. For example, TERS studies revealed nanoscale chemical images of various molecules containing a benzene ring such as thiophenol or carbon nanotubes. Additionally, heterogeneous catalytic reactions at the solid−liquid interface were investigated in a new way to gain a deeper insight into electrochemical processes. Furthermore, TERS measurements expanded our knowledge of several redox compounds and enabled new insights into various chemical transformations. Despite substantial progress, TERS in liquids is not yet a routine measurement method, and there are still several challenges to solve before TERS can unleash its full potential.

The puepose of the present review article is to outline the development of vibrational spectroscopy and electronic spectroscopy in condensed phase for the last 30 years or so. Recent advances in far ultraviolet, near infrared, far infrared/terahertz/low frequency Raman, and Raman spectroscopy are reviewd. The feilds of Raman spectroscopy are so wide that in this article only surface enhanced Raman scattering and tip enhanced Raman scattering, and application of Raman spectroscopy to medical sciences are presented. It is of note that about 30 year ago far ultraviolet spectroscopy for condensed phase, terahertz spectroscopy and tip enhanced Raman scattering were in the stage of ``before dawn''. Application to basic science of near infrared spectroscopy was also not develped. In each session after the brief history of each spectroscopy, its characteristic and advantages are described. Then, examples of applications are introduced. Some emphasis is put on quantum chemical calculations and instruments which we newly developed. Finaly, future prospects of vibrational spectroscopy and electronic spectroscopy in condenseed phase is discussed.
