A number of molecularly specific models for the oxygen-evolving complex in photosystem II (PSII) and of manganese-substrate water intermediates that may occur in this process have been proposed recently. We summarize this work briefly. Fourier transform infrared techniques have emerged as fruitful tools to study the molecular structures of Y(Z) and the manganese complex. We discuss recent work in which mid-IR (1000-2000 cm(-1)) methods have been used in this effort. The low-frequency IR region (<1000 cm(-1)) has been more difficult to access for technical reasons, but good progress has been made in overcoming these obstacles. We update recent low-frequency work on PSII and then present a detailed summary of relevant manganese model compounds that will be of importance in understanding the emerging biological data.
最近已经提出了许多关于光系统II（PSII）中放氧复合物以及该过程中可能出现的锰-底物水中间体的分子特异性模型。我们简要总结这项工作。傅里叶变换红外技术已成为研究Y（Z）和锰复合物分子结构的有效工具。我们讨论了最近在这项工作中使用中红外（1000 - 2000 cm⁻¹）方法的研究。由于技术原因，低频红外区域（<1000 cm⁻¹）更难研究，但在克服这些障碍方面已经取得了良好进展。我们更新了关于PSII的最新低频研究，然后详细总结了相关的锰模型化合物，这些化合物对于理解新出现的生物学数据将具有重要意义。
