Dynamics of Molecule-Surface Reactions (DST)


Admission requirements

Elective course in MSc Chemistry, MSc Life Science and Technology.

For students with a BSc in MST, LST or equivalent who have completed at least the second year MST course theoretical chemistry.


This course addresses results of dynamics calculations on molecule-surface reactions, based on recent papers from the scientific literature. Subjects include: the effect of the collision energy and the initial rovibrational state of the reacting molecule on the dissociative chemisorption of diatomic molecules (e.g. H2, N2, and O2) and a polyatomic molecule (CH4), the effect of "alignment" and "orientation" on the dissociative chemisorption of diatomic molecules (H2 and NO), and the final state distribution” in Eley-Rideal reactions.

Course objectives

After the course, students:

  • are able to read and analyse specialist literature within the field of molecule-surface reaction dynamics

  • are able to describe the state-of-the-art of experiments and theory in the field

  • are able to interrelate theoretical and experimental work done on similar systems

  • can present orally a resume of a scientific article from the field with aid of presentation software (e.g. MS PowerPoint) highlighting crucial aspects and including relevant details

  • can articulate critical questions and accurate answers about the contents of such scientific articles

  • can explain various types of motivations used to justify research performed in this field


Schedule information can be found on the website of the programmes.

You will find the timetables for all courses and degree programmes of Leiden University in the tool MyTimetable (login). Any teaching activities that you have sucessfully registered for in MyStudyMap will automatically be displayed in MyTimeTable. Any timetables that you add manually, will be saved and automatically displayed the next time you sign in.

MyTimetable allows you to integrate your timetable with your calendar apps such as Outlook, Google Calendar, Apple Calendar and other calendar apps on your smartphone. Any timetable changes will be automatically synced with your calendar. If you wish, you can also receive an email notification of the change. You can turn notifications on in ‘Settings’ (after login).

For more information, watch the video or go the the 'help-page' in MyTimetable. Please note: Joint Degree students Leiden/Delft have to merge their two different timetables into one. This video explains how to do this.

Mode of instruction

Seven discussion meetings of two hours each.

Assessment method

Exam (70%) and presentation by students (30%). The exam will be either an oral or a written exam, depending on the number of students that intend to take the exam.

Reading list

Scientific papers from the literature as outlined in the syllabus.


From the academic year 2022-2023 on every student has to register for courses with the new enrollment tool MyStudyMap. There are two registration periods per year: registration for the fall semester opens in July and registration for the spring semester opens in December. Please see this page for more information.

Please note that it is compulsory to both preregister and confirm your participation for every exam and retake. Not being registered for a course means that you are not allowed to participate in the final exam of the course. Confirming your exam participation is possible until ten days before the exam.

Extensive FAQ's on MyStudymap can be found here.


Prof. dr. G.J. Kroes,


This biennial course will be given in 2023-24. The course is scheduled again for academic year 2025-26.
