“…Nonlinearities in the Stark tuning rate are thus introduced at the microscopic level by the varying degree of electronic conjugation. Indeed, in water and DMSO, which generate the largest electric field (Table I), the average deviation from planarity of acetophenone (16 • < φ < 17 • ) is larger than the average for the other five solvents (6 • < φ < 11…”

“…Indeed, the area under the A 1 -band has been shown to be weakly dependent on the environment [113] and efficient for quantification in biological samples where the polarity of the environment can change to a large extent [14]. On the other hand, the energy position of the bands, including the E-bands, can vary depending on the environment [114]. Figure 17) and thiol-specific (49, Figure 17) groups have been appended to the cyclopentadienyl rhenium tricarbonyl complex.…”

“…One promising method in this regard is vibrational Stark spectroscopy, [2] which capitalizes on the fact that vibrational transitions have an intrinsic dependence on local electrostatic environment and uses an infrared (IR) probe that has a well-defined, localized vibrational mode to sense local electric field amplitude through the response of the frequency. [3] For example, the vibrational Stark effect has been used to determine the local electric field at protein interfaces and to monitor protein conformational transitions and dynamics. [4] While the theoretical underpinning of this methodology is straightforward, in practice the application of vibrational Stark spectroscopy to biological systems is currently limited by the availability of suitable vibrational probes.…”
