Henrik Ottosson
Physical organic chemist at Uppsala University, Sweden, with additional interests in urban science and sustainability. Special research focus on excited state aromaticity & antiaromaticity effects, both the fundamental and applied aspects.
- The smallest and most abundant aromatic species in the Universe, H3+, has some truly crucial functions. It also has a really high first electronic excitation energy; 19.3 eV. Check out why this is the case in our latest paper in @chemicalscience.rsc.org pubs.rsc.org/en/content/a...
- The slides at the Winter School of icesaa-4.in are now available to download; in total 388 slides on intro (anti)aromaticity & descriptors, intro photochemistry, ultrafast spectroscopy, computations of excited states, excited state PES features, organic photochem & pitfalls ...🧵

- Please remember to block September 22 - 25, 2027, in your calendar for ICESAA-5 to be held in Osaka, Japan, by Prof. Shohei Saito & team. More info to be posted in the next few months, yet be prepared, it will also be a really stimulating conference!!!
- Here the conference photo at the 4th International Conference on Excited State Aromaticity & Antiaromaticity @icesaa-4.bsky.social held at IISER-TVM on Jan 8 - 11. An absolutely fantastic conference - thanks a lot @maheshhariharan.bsky.social & team!!!

- Now in the special issue on Physical Organic Chemistry of J. Org. Chem.. We explore which factors determine whether a certain heteroaromatic compound has its first excited states (T1 & S1) of npi* or pipi* character, and identify six factors. More to follow! pubs.acs.org/doi/10.1021/...

If a city increased its road capacity by 10% then driving in that city went up by 10%.” Still one of the best articles on why building bigger roads leads to more driving.
