Journal ArticleDOI
Infrared Spectra of H+(H2O)5-8 Clusters: Evidence for Symmetric Proton Hydration
Jyh-Chiang Jiang,Yi-Sheng Wang,Hai-Chou Chang,Sheng H. Lin,Yuan T. Lee,Gereon Niedner-Schatteburg,Huan-Cheng Chang +6 more
TL;DR: In this article, a vibrational predissociation spectroscopy and ab initio calculations of protonated water clusters from a supersonic expansion were performed at the B3LYP/6-31+G* level.
Journal ArticleDOI
Matrix-assisted laser desorption/ionization (MALDI) mechanism revisited
Wei Chao Chang,Ling Chu Lora Huang,Yi-Sheng Wang,Wen-Ping Peng,Huan-Cheng Chang,Nien Yeen Hsu,Wen-Bin Yang,Chung-Hsuan Chen +7 more
TL;DR: This work considers a pseudo proton transfer process during crystallization as a primary mechanism for producing analyte ions in MALDI and proposes an energy transfer induced disproportionation (ETID) model to explain the observation of an equal amount of positive and negative ions produced in MalDI for large biomolecules.
Journal ArticleDOI
Vibrational predissociation spectra and hydrogen-bond topologies of H+(H2O)9–11
Chih-Kai Lin,Chih-Che Wu,Yi-Sheng Wang,Yuan T. Lee,Huan-Cheng Chang,O Jer-Lai Kuo,Michael L. Klein +6 more
TL;DR: The results, combined with previously acquired spectra, show a systematic change in hydrogen-bond topology from tree-like, single-ring, multiple-ring to cage-like isomers (and their mixtures) as the cluster size increases from n = 5 to n = 11.
Journal ArticleDOI
Infrared spectra and isomeric structures of hydroxide ion-water clusters OH- (H2O)1-5: a comparison with H3O (H2O)1-5
C. Chaudhuri,Yi-Sheng Wang,Jyh-Chiang Jiang,Yuan T. Lee,Huan-Cheng Chang,Gereon Niedner-Schatteburg +5 more
TL;DR: In this paper, the authors used vibrational predissociation spectroscopy in conjunction with ab initio calculations based on density functional theory (DFT) to investigate size-selected hydroxide ion water tetramers and pentamers produced by a supersonic expansion.
Journal ArticleDOI
Matrix-assisted laser desorption/ionization mass spectrometry of polysaccharides with 2',4',6'-trihydroxyacetophenone as matrix.
Nien-Yeen Hsu,Wen-Bin Yang,Chi-Huey Wong,Chi-Huey Wong,Yuan-Chuan. Lee,Reiko T. Lee,Yi-Sheng Wang,Chung-Hsuan Chen,Chung-Hsuan Chen +8 more
TL;DR: 2',4',6'-trihydroxyacetophenone (THAP) is a good matrix for MALDI time-of-flight MS analysis of polysaccharides with broad mass range for matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS).
