	Objectives
	THE COURSE AIMS TO PROVIDE THE BASIC KNOWLEDGE OF MOLECULAR QUANTUM MECHANICS THAT IS USEFUL TO UNDERSTAND THE FORMATION MECHANISMS, THE STRUCTURE AND THE SYMMETRY PROPERTIES OF A SIMPLE MOLECULE, AS WELL AS THE LINK WITH INFRARED ABSORPTION (OR EMISSION) SPECTRA. KNOWLEDGE ACQUIRED AND ITS COMPREHENSION: STUDENTS WILL ACHIEVE A GOOD GENERAL KNOWLEDGE OF MOLECULAR PHYSICS AND MOLECULAR SPECTROSCOPY. MOREOVER, THEY WILL UNDERSTAND THE IMPORTANCE OF LASER SPECTROSCOPY FOR THE DETERMINATION OF MOLECULAR PARAMETERS AND FOR THE DIAGNOSTIC OF GASEOUS ENVIRONMENTS. APPLYING KNOWLEDGE AND UNDERSTANDING: STUDENTS WILL UNDERSTAND THE RELEVANCE OF QUANTUM PHYSICS AND MOLECULAR SPECTROSCOPY FOR THE STUDY OF EARTH AND PLANETARY ATMOSPHERES. THE CAPACITY TO APPLY THE KNOWLEDGE WILL BE STIMULATED THROUGH A NUMBER OF EXAMPLES OF REAL SPECTROSCOPIC APPLICATIONS WITH A VARIETY OF DIFFERENT PURPOSES.

	Teaching Methods
	LECTURES (FOR A TOTAL OF 40 HOURS) ON THE VARIOUS TOPICS CHARACTERIZING THE COURSE, WITH FREQUENT REFERENCE TO REAL PHENOMENA AND EXPERIMENTS. NUMERICAL EXERCISES ARE ALSO PLANNED.

	Verification of learning
	ORAL EXAMINATION, WITH TIME DURATION OF ABOUT 30 MINUTES. THE EXAMINATION CONSISTS OF THREE QUESTIONS, FOR FOR EACH OF THE DIFFERENT CHAPTERS OF THE PROGRAM. THE EXAMINATION IS AIMED AT TESTING THE LEVEL OF KNOWLEDGE, COMPREHENSION AND SKILLS RELATED TO THE TOPICS OF THE COURSE.
