Raman spectroscopic characterization of selenium N-heterocyclic carbene compounds

Enhanced Solar Evaporation Using a Scalable MoS2‐Based Hydrogel for Highly Efficient Solar Desalination

“…As shown in Figure 4a, two obvious characteristic peaks appear at 374 and 408 cm −1 , corresponding to the in‐plane ( ) and out‐of‐plane ( A 1 g ) Raman peaks of Mo−S bond in MoS 2 , respectively [15] . Comparably, the two Raman characteristic peaks of SMoS 2 ‐PH red‐shifted, which may be caused by the interaction between MoS 2 and hydrogel [31] …”

“…[15] Comparably, the two Raman characteristic peaks of SMoS 2 -PH redshifted, which may be caused by the interaction between MoS 2 and hydrogel. [31] The surface hydrophilicity and mechanical stability of the SMoS 2 -PH were subsequently investigated. It was observed that the droplet could be completely absorbed by the SMoS 2 -PH within about 40 millisecond (ms) (Figure 4b and Movie S1, Supporting Information).…”

Enhancing the Chemical Stability and Photovoltaic Properties of Highly Efficient Nonfullerene Acceptors by Chalcogen Substitution: Insights from Quantum Chemical Calculations

“…The regions at 459 and 230 cm –1 are due to Se cyclic and chain structures, respectively, and those at 580–590 cm –1 are characteristic of Se–C vibration modes . For the Y6–2Se structure, these bands are present at 287 and 1100 cm –1 , corresponding to SeC and Se–C, respectively.…”

Characterization of three different benzimidazolium ligands and their organo-selenium complexes by using density functional theory and Raman spectroscopy

“…9,10 However, available literature reveals that these above-illustrated approaches do not provide a direct detection pathway within one certain analytic cycle as these techniques have many limitations like consumption, require more sample, expensive, often require complex sample preparation and various intermediate steps which are expensive and laborious. 11,12 Raman spectroscopy has been used to minimize the limitations of the above illustrated techniques as it is inexpensive, based on nondestructive interaction between light with chemical bonds within a material, requires no complex sample preparation and requires sample only in a small amount. Raman spectroscopy has also been used to study crystallinity, chemical structure, polymorphism, phase, molecular interactions and to minimize the limitations in the characterizations of organometallic compounds such as dimethylselone, seleno urea, organo selenols, organo selenium carbene, organo selenium halides and transition organo selenium compounds.…”
