By simulating the vibrational spectra of water clusters of increasing size using quantum-derived semiclassical spectroscopy, Ceotto and his team looked to see when the spectra matched that of bulk water. ‘With just a few water molecules, which make up to two solvation shells, the physics of vibration in liquid water is recovered,’ explains Ceotto. In a simple description of water, individual molecules can be thought of as being a double donor and double acceptor of hydrogen bonds. And although Ceotto’s team’s findings show that tetrahedral coordination is necessary, they suggest it is insufficient on its own to be reflective of bulk water.

Congratulations to the 118 members of the 2021 class of OSA Fellow Members, who will be recognized at OSA conferences throughout the year for scientific, engineering and technological contributions, as well as industry leadership and service to OSA and the global optics community.
The 2021 class of Fellows reflects the diverse and inclusive community that OSA serves. A record 261 nominations were received, making this program very competitive as no more than 10% of OSA’s total membership may be elected as Fellows. For more information, contact the OSA Awards Office (awards@osa.org; +1 202.416.1960) or go to www.osa.org/fellows.. Nominations for 2022 Fellows are due by 15 June 2022.
