Ultrafast Spectroscopy: Applications and Instrumentation
Virtual Only
Division of Physical Chemistry
Ultrafast spectroscopy today spans a broad range of applications, including photo physics and photochemistry of organic and inorganic materials, light-harvesting and energy-conversion processes, etc. This symposium will emphasize how time-resolved measurements reveal mechanistic insight that is inaccessible to steady-state approaches, thereby enabling rational design of functional materials and control of excited-state pathways. Topics will range from widely accessible tabletop femtosecond laser systems and broadband pump-probe techniques to cutting-edge capabilities enabled by high-harmonic generation sources, free-electron lasers, and XUV/X-ray facilities. Emphasis will be placed on methodological innovation, including pulse generation and compression, multidimensional spectroscopy, time-resolved microscopy, advanced detection schemes, and emerging data-analysis strategies.
Symposium Features
Present your research in your local time zone
- Inviting early career researchers from across the globe to deliver flash presentations.
Get exposure and recognition
- As a presenter, you will receive a certificate of participation at ACS Meetings.
- Abstracts will be listed in the CAS database and can be added to your Google Scholar profile.
Symposium schedule
- The symposium will feature multiple sessions from August 23-27.
- Sessions will be scheduled in convenient daytime hours in multiple regions such as Asia, the Middle East, Africa, and Oceania; however, for the Americas, these sessions will be in the early mornings.

Frequently Asked Questions
What are Flash presentations?
They are brief, impactful, and convey information about a novel protocol, perspective, technique, or research results. For instance, one Flash Talk may describe an innovative interdisciplinary research outcome. Another may describe results for a pilot/prototype study.
Can I submit an abstract if I'm not an early career researcher?
Researchers from all career stages are welcome to present their work. However, the format of the presentation will be 8 minutes of talk followed by 2 minutes of Q/A.
What is the submission deadline for abstracts?
The submission deadline for abstracts is March 30, 2026, 11:59 PM ET.
What is the required format for abstracts?
Abstracts should be 2500 characters or less and include the title, author(s), and a concise description of your research.
Can I include images or figures in my abstract?
Yes, limited use of images or figures is permitted to enhance your abstract's content.
When will I know if my abstract is accepted?
Presenters can expect to receive their acceptance notices approximately 3 months before the meeting. Scheduling notices are sent periodically starting approximately 2 months before the meeting.
What if I can't attend the symposium on the scheduled date?
The Global Virtual Symposia do not have a provision for recorded talks. Presenters can only present in real-time. However, for any rescheduling requests, please reach out to our symposium chairs and organizers beforehand.
Do I need to register separately if my abstract is accepted?
Yes, accepted presenters will have to register for ACS Fall 2026. Symposium organizers will reach out to confirm their participation.
