Rhodamines constitute a class of dyes extensively investigated and applied in various
contexts, primarily attributed to their high luminescence quantum yield. This study delves …

Many photoinduced excited states' relaxation processes and chemical reactions occur at
interfaces and surfaces, including charge transfer, energy transfer, proton transfer, proton …

The well-known formalism for Sum-Frequency Generation (SFG) reflected or transmitted by
a three-layer system involves three equations defining the emitted SFG intensity, the …

Photoinduced relaxation processes at interfaces are intimately related to many fields such
as solar energy conversion, photocatalysis, and photosynthesis. Vibronic coupling plays a …

Doubly resonant sum frequency generation (DR-SFG) serves as a potent characteristic
technique for probing the electronic spectra and vibronic coupling of molecules on surfaces …

We present a general formalism to model and calculate linear and nonlinear optical
processes in composite systems, based on a graphical representation of light-matter …

Silicone sealants and adhesives are extensively used in construction, automotive, industrial,
and electronic applications because they exhibit excellent mechanical properties, strong …

A bipartite system is defined as two microscopic entities being able to exchange energy.
When excited by light, the complete optical response functions at first (polarizabilities) and …

The transform technique applied to the analysis of doubly resonant sum-frequency
generation (DR-SFG) spectra is extended to include Herzberg–Teller (HT) vibronic modes …

Vibrational sum frequency generation can provide valuable structural information at surfaces
and buried interfaces. Relating the measured spectra to the complex-valued second-order …
