2019年7月1日 · In the present report, we employ selected-ion photodissociation spectroscopy to obtain the infrared spectrum of the methaniminium cation, H 2 C NH 2+. Methanimine was detected in the interstellar medium (ISM) in 1973 [25], and is an intermediate in the Strecker synthesis of amino acids [26].

2015年8月16日 · Electron quantum dynamics during a non-adiabatic process are examined. The Ehrenfest method with configuration interaction theory is used. The excited state internal rotational motion of H 2 CNH 2+ is investigated as a model reaction. The fast intramolecular electron transfer between carbon and nitrogen atoms is observed.

For example, water is H 2 O, meaning it contains two hydrogen atoms and one oxygen atom. Find atomic masses: look up the atomic masses of each element present in the compound. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu).

逐步计算摩尔质量; 首先，计算 h 2 cnh 2 中每个原子的数量： h: 4, c: 1, n: 1. 然后，查找元素周期表中每个元素的原子量： h: 1.00794, c: 12.0107, n: 14.0067 现在，计算原子数与原子量的乘积之和：

2022年5月1日 · Overview: This paper presents a spectroscopic study of H 2 CNH + and its isomer, the aminomethylene cation. Core findings: The vibrational transitions and the relative abundances of the two isomeric ions of H 2 CNH + and H 2 CNH +. Significance: Our study shows that both isomers should be included in astrochemical models.

2019年4月1日 · The methaniminium ion (H 2 C [dbnd]NH 2⁺ ) was produced in a pulsed electrical discharge supersonic expansion of argon saturated with ethylenediamine vapor. It was identified and mass selected in a...

H2CNH •+ plus C2H4: relative enthalpies and reaction pathways leading to products CH2CNH2 + plus CH3 • (in red), H2CNH2 + plus C2H3 • (in green and pink) and CH2CHNHCH2 + plus H • (in blue). The...

2021年8月1日 · Experimental and theoretical studies are presented on the reactivity of H2CNH•+ (methanimine) and HCNH2•+ (aminomethylene) with ethene (C2H4).

A quantum-chemical study of some properties and reactions of H 2 CN −, H 2 CN +, H 2 CNH 2+, H 2 CNH, and HCN, using small and intermediate-sized sets of basis functions.
