The widespread use of nonlinear optical (NLO) materials for contemporary technologies has sparked intense interest in their production with the creation a continuous endeavor. In this theoretical study, we investigate NLO responses doped superalkali (SA) metal salts planar boron sheets (PBSs). We consider four different substrates (B[Formula: see text], B[Formula: text]F 3 , and ) to create 12 new surfaces (1-12) by doping SAs (Li 2 F, Li OF, O them. optimize geometries these analyze frontier molecular orbitals (FMOs) natural bond (NBO) obtain insights into global chemical reactivity. also examined ranging as 1.22–[Formula: 3.39–[Formula: [Formula: text][Formula: text]e.s.u. Our results reveal that exhibit stronger compared undoped surfaces, strongest response is found -doped surface. role various segments FMOs investigated using TDOS PDOS spectral analyses. To comprehend relationship between SA molecule more effectively, non-covalent interaction (NCI) investigation carried out. Additionally, Time-dependent DFT (TD-DFT) simulations are done UV–Vis analysis observe significant redshifts up 1050[Formula: text]nm. All SA-doped thermodynamically stable improved responses, so proposed be used during construction advanced responses.

This study investigates the impact of thermal decomposition on ion mobility spectrum L-alanine using spectrometry (IMS) and computational methods. By employing a post-injection delay system, we examined evolution peaks corresponding to products their interaction with protonated alanine. Experimental results revealed that observed spectra predominantly feature isomers adduct ions. Computational analysis Density Functional Theory (DFT) predicted thermodynamically favored structures stabilities these products. Findings indicate protonation at nitrogen site in alanine is more stable than oxygen site, correspond adducts formed ammonium Further investigations showed generates ammonia, contributing formation new research provides insights into behavior amino acids under conditions implications for analytical chemistry biochemistry.
