Abstract

High-resolution absorption spectra of the S1←S0000 transition of buffer-gas-cooled magnesium-phthalocyanine, zinc-phthalocyanine, and chloroaluminum-phthalocyanine are presented. The low temperature achieved through buffer gas cooling allowed the observation of a partially resolved rotational structure in each spectrum. We compare these structures with the previously observed high-resolution spectrum of free-base phthalocyanine. Despite the similar molecular structures of these molecules, the spectral characteristics of the rotational envelope vary depending on the individual molecular structures.

缓冲气冷却金属酞菁的高分辨率电子光谱学

本文展示了缓冲气冷却的镁-酞菁、锌-酞菁和氯铝-酞菁的 S1←S0000 转变的高分辨率吸收光谱。通过缓冲气冷却实现的低温使我们能够在每个光谱中观测到部分解析的旋转结构。我们将这些结构与之前观测到的游离基酞菁的高分辨率光谱进行了比较。尽管这些分子的分子结构相似，但旋转包络的光谱特征却因分子结构的不同而各异。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
