Welcome to the 75th ISMS! We are excited to meet you for some great science this summer, whether you attend in-person or virtually.

All speakers (whether in-person or remote) must upload a video of their talk by June 12, see instructions here. You must also upload the Powerpoint/PDF of your talk by 11:59pm CDT the day before your talk (whether in-person or virtual). Detailed instructions for presentations are available here.

We are taking several steps to minimize the risk of COVID during the symposium: please see details on our COVID Strategy page.

An attendee portal is now available, where you can view on-line talks, look at your virtual "registration packet", or print a receipt or certificate of participation.


The International Symposium on Molecular Spectroscopy is the premier annual meeting in this exciting and interdisciplinary field. The symposium uniquely combines plenary talks from world leaders in the field with parallel sessions comprising shorter talks, many presented by graduate students, and fosters a collegial and collaborative atmosphere with a multitude of formal and informal interactions. Registration and housing costs are kept low to enable entire research groups to attend, and in fact most senior people in the field gave their very first conference presentation at this symposium (to a very friendly audience). A wide range of topics is covered, from theory to experiment, from gas-phase to condensed-phase, from low resolution to ultra-high resolution, from the microwave to the ultraviolet, and from fundamental science to applications such as astronomy and atmospheric science. Each year's meeting also includes three "mini-symposia" on topics of special interest.
