Spectroscopy and Quantum Chemical Studies
Spectroscopy and Quantum Chemical Studies is a research topic within Atomic and Molecular Physics, and Optics. Science Explorer counts 97k research works in it since 1950. 21.6% of them reached the world's top 10% most cited for their field and year.
This cluster of papers explores the role of quantum coherence in photosynthetic energy transfer, as well as its effects on energy migration, ion interactions, hydrogen bonding, and vibrational dynamics in aqueous systems. The research also delves into the impact of ions on surface interfaces and the behavior of molecular systems under quantum coherence.

How concentrated that is
The same countries as shares of everything the list above accounts for. A node where two countries do two thirds of the work and one spread evenly across twelve read alike as a ranking and not at all alike here.
