In the last few decades, Spectroscopy and its application dramatically diverted science in the direction of brand new era. This book reports on recent progress in spectroscopic technologies, theory and applications of advanced spectroscopy. In this book, we (INTECH publisher, editor and authors) have invested a lot of effort to include 20 most advanced spectroscopy chapters. We would like to invite all spectroscopy scientists to read and share the knowledge and contents of this book. The textbook is written by international scientists with expertise in Chemistry, Biochemistry, Physics, Biology and Nanotechnology many of which are active in research. We hope that the textbook will enhance the knowledge of scientists in the complexities of some spectroscopic approaches; it will stimulate both professionals and students to dedicate part of their future research in understanding relevant mechanisms and applications of chemistry, physics and material sciences.

In the past few weeks, the world witnessed how epidemic outbreaks of COVID-19 turned into a pandemic. To synchronize the research efforts and to identify the research gaps in cutting edge priority areas, WHO (World Health Organization) has come up with a research blueprint with a substantial timeline and roadmap. To understand the background and progress of this roadmap, a comprehensive analysis of published researches on COVID-19 has become essential. With this motivation, this paper analyzes all the available literature from the Scopus database to discover the trend and unleash the pattern and nature of the studies. This study applies thematic mapping to find relationship among research topics, importance, and relevance. Keywords analysis and co-word analysis are used to build a semantic and scientific field map and Lotka's Law to measure the productivity patterns. This study also employs Citation analysis, H-Index, and Co-author analysis to find out the top authors, their affiliations, quality, quantity, and impact of the research done. The study reveals that there is a significant surge in publications in recent times. In 2020 alone, there are 479 publications (as of March 26, 2020) indexed in Scopus. A total of 1,277 keywords have been used. Alongside COVID-19 related keywords, researchers also investigated SARS, SARS CoV 2, MERS CoV, and other diseases. The Lancet, Virology, Journal of Medical Virology and Antiviral Research are found to be among the top journals. Countrywise, China, USA, and Germany are the top publishing countries, while the universities in China, specifically in Wuhan, are leading the research by numbers. The largest share of scientific outputs during the analysis period is in the form of 'Journal Articles' (60.65%) and multiple-authored publications dominate (79.31%) over single-authored publications (20.69%). A lack of preventive studies and multidisciplinary social science is observed. The impacts are not properly documented through scientific publications, as evidenced by our analysis. Researchers may consider these less-studied areas in their future scientific endeavors to fulfill the gaps.
