Infrared Spectroscopy and Anharmonic Vibrational Analysis of (H2O–Krn)+ (n = 1–3): Hemibond Formation of the Water Radical Cation
Autor: Toshihiko Maeyama, Qian-Rui Huang, Asuka Fujii, Jer-Lai Kuo, Tomoki Nishigori, Jing-Min Liu, Marusu Katada
Publikováno v: The Journal of Physical Chemistry Letters. 12:7997-8002
The hemibond is a nonclassical covalent bond formed between a radical (cation) and a closed shell molecule. The hemibond formation ability of water has attracted great interest, concerning its role in ionization of water. While many computational stu

Cooperativity of the Activated CH/π Interaction Probed through CH Stretching Vibrations in Phenol–(Acetylene)n (∼16 ≤ n ≤ ∼30) and (Acetylene)n+ (10 ≤ n ≤ 70) Clusters
Autor: Takashi Chiba, Asuka Fujii, Marusu Katada
Publikováno v: The Journal of Physical Chemistry A. 125:3885-3891
The acidity of acetylene CH is stronger than that of alkane CH, and the attractive interaction between an acetylene CH with π-electrons, which shows a clear hydrogen bond property, is called activated CH/π interaction. In this study, cooperative en

Vibrational Coupling in Solvated H3O+: Interplay between Fermi Resonance and Combination Band
Autor: Tomoki Nishigori, Jer-Lai Kuo, Marusu Katada, Ying Cheng Li, Asuka Fujii, Qian-Rui Huang
Publikováno v: The Journal of Physical Chemistry Letters. 11:10067-10072
Complex vibrational features of solvated hydronium ion, H3O+, in 3 μm enable us to look into the vibrational coupling among O-H stretching modes and other degrees of freedom. Two anharmonic coupling schemes have often been engaged to explain observe

Infrared spectroscopic observation of the McLafferty rearrangement in ionized 2-pentanone
Autor: Ryo Yasumoto, Asuka Fujii, Yoshiyuki Matsuda
Publikováno v: Physical Chemistry Chemical Physics. 22:19230-19237
The McLafferty rearrangement is a well-known process in mass spectrometry. In ionization of organic molecules containing a carbonyl group, β cleavage occurs following transfer of a hydrogen atom of aliphatic CH at the γ position to the carbonyl gro
