Haemoglobin (Hb) is widely known as the iron-containing protein in blood that is essential
for O 2 transport in mammals. Less widely recognised is that erythrocyte Hb belongs to a …

Electric fields affect any process or transition that involves the movement of charge. Stark
spectroscopy is a general term describing the study of spectral changes in the presence of …

Metal–organic frameworks (MOFs) are promising platforms for heterogeneous tethering of
molecular CO2 reduction electrocatalysts. Yet, to further understand electrocatalytic MOF …

2 1 Introduction the most salient points are just that a molecule can exist in a variety of states
depending on how its electrons are distributed among a set of molecular orbitals, and that …

It is well-known that the C⋮ N stretching vibration in acetonitrile is sensitive to solvent.
Therefore, we proposed in this contribution to use this vibrational mode to report local …

Vibrational probes can provide a direct readout of the local electrostatic field in complex
molecular environments, such as protein binding sites and enzyme active sites. This …

The photosynthetic processes that lead to water oxidation involve an evolution in time from
photon dynamics to photochemically-driven electron transfer to coupled electron/proton …

Vibrational Stark effects, which are the effects of electric fields on vibrational spectra, were
measured for the C− N stretch mode of several small nitriles. Samples included …

Vibrational spectroscopy provides a direct route to the physicochemical characterization of
molecules. While both IR and Raman spectroscopy have been used for decades to provide …

We report the first measurement of the vibrational Stark effect in a protein, providing
quantitative information on the sensitivity of a vibrational transition to an applied electric …
