Hydrogen Bonding: From Biological Systems To Interstellar Medium

Intermolecular interactions are very vital in the elucidation of structure and properties of many biological molecules like water, DNA, proteins, etc. They are embedded in chemical and biological systems by nature. Due to their importance, they are well-studied and understood to an extent. Some of these interactions are critical in maintaining the 3-dimensional structure of

Molecules In Space: Physics, Chemistry And Biology

The collaboration between spectroscopists and astrophysicists initiated in the 18th century with the purpose of assigning the Fraunhofer lines in the solar spectrum to atomic transitions has remained fruitful, successful and ever fascinating. This collaboration has resulted in the unique detection of over 200 different molecular species in the interstellar medium (ISM) and circumstellar envelopes.
