Abstract The Beer‐Lambert law is unquestionably the most important law in optical
spectroscopy and indispensable for the qualitative and quantitative interpretation of …

Optical chemical imaging seeks to nondestructively acquire spatially resolved chemical
information without the use of labels or probes. The combination of vibrational mid-infrared …

Vibrational spectroscopy and imaging promise molecular information that can be rapidly
acquired without the need for specialized stains or dyes, thereby potentially simplifying and …

Since its inception in the mid-1960s, the T-matrix method has been one of the most versatile
and efficient numerically exact computer solvers of the time-harmonic macroscopic Maxwell …

Chemical imaging combines the spatial specificity of optical microscopy with the spectral
selectivity of vibrational spectroscopy. Mid-infrared (IR) absorption imaging instruments are …

It has been well recognized that infrared spectra of microscopically heterogeneous media do
not merely reflect the absorption of the sample but are influenced also by geometric factors …

Beer's law assumes a linear dependence of absorbance on concentration, accordingly the
index of absorption and the molar attenuation coefficient are material properties and the …

We present the theoretical basis for a profound upgrade of the method of absorbance band
fitting (“band deconvolution”), which requires only minute changes in the code of …

Mie-type scattering features such as ripples (ie, sharp shape-resonance peaks) and wiggles
(ie, broad oscillations), are frequently-observed scattering phenomena in infrared …

The assembly studies of high-nuclear clusters have received much interest in recent years
due to their targeted synthesis for some special usages. A Schiff base ligand 2-[N-(2 …
