The Cover Feature illustrates that surface enhanced Raman spectroscopy (SERS) can be used to investigate low frequency vibrational interactions between gold surfaces and dissolved halides in water, opening up new means to investigate the aggregation of nanoparticles in aqueous environments. Experiments with sodium halide salts indicate resulting SERS bands correlate with the bond‐strength of the corresponding covalent interaction. More information can be found in the Communication by M. Y. Chan et al. on page 24 in Issue 1, 2018 (DOI: 10.1002/cphc.201700798).
