Electron Energy Loss Spectroscopy (EELS) is a powerful surface-sensitive technique utilized to probe the vibrational modes of atoms and molecules adsorbed on or intrinsic to material surfaces. By analyzing the characteristic energy lost by incident electrons, EELS provides crucial insights into surface chemistry, adsorption processes, and the dynamics of surface vibrations, essential for understanding phenomena from catalysis to thin film growth.

Vibrational spectroscopy of solids is a powerful analytical technique employed to investigate the molecular and lattice vibrations within solid-state materials. This method, often utilizing techniques like Raman and Infrared spectroscopy, provides crucial insights into a material's atomic structure, chemical bonding, and fundamental physical properties, aiding in characterization and research across various scientific disciplines.

Explore the fundamental principles of molecular symmetry and its profound influence on molecular spectroscopy. This field delves into how the inherent symmetry elements of a molecule dictate its spectroscopic properties, enabling the precise interpretation of vibrational, rotational, and electronic spectra. Understanding symmetry in molecules through advanced techniques like vibrational spectroscopy is crucial for accurately determining molecular structure, predicting chemical behavior, and applying group theory concepts to chemical systems.

This research investigates intriguing anomalies observed in the infrared spectra of inorganic compounds. It specifically examines how these deviations manifest when samples are prepared using the widely adopted potassium bromide (KBr) pellet technique, offering critical insights for accurate material characterization and understanding unexpected spectral behaviors.
