Course unit content

This course intends to explore the foundations of selected spectroscopic methods normally used to investigate molecular properties. Ground and excited state properties as well as their interactions with the environment will be dealt with, with steady state and time resolved methodologies. The spectroscopic techniques dealt with in this course are endowed with time resolution which is adequate for studying transient or unstable molecular states.

Radiation-Matter interactions
Time resolved optical methods
Excited state processes
Fluorescence spectroscopy methods
Mechanisms and dynamics of competitive de-excitation
Photothermal spectroscopies
Single molecule detection
Laboratory practice

Teaching methods

The course consists in a series of lectures covering the fundamentals of the spectroscopic methodologies. For those methods available at this Department, laboratory practice will be taken.
Students will have to perform four experiments on molecular systems, that enable to follow relevant photophysical processes.

Assessment methods and criteria

Assessment of the level of learning will be done on the basis of the lab reports that the students, divided into groups, will elaborate.
Each report will be discussed with the workgroup components.
