This course teaches the basic principles of molecular and chemical physics which are essential for building and understanding experiments in molecular, physical and analytical chemistry. This two-term course is divided into 4 topics:, 1) molecular beam; 2) mass spectrometry, 3) lasers and optical methods; 4)surface scanning techniques. In the first part, underlying physical principles of these methods will be introduced, and in the second part, examples of modern experiments based on the above techniques will be reviewed. Particular examples of the topics introduced in this first part are: molecular beam techniques; basic principles of mass analyzers, magnetic and electric sector fields, time-of-flight spectrometers, quadrupoles etc.; theory and examples of lasers; tunneling electron and atom force microscopy.
