一种新的微型高压池已被开发用于光谱研究的有机金属化合物浸渍到聚合物薄膜和气体之间的反应，如N2或H-2在环境温度和20 K之间的任何温度。在190 K下，聚乙烯膜（PE）中的Fe（CO）与N2和H2-分别发生光化学反应生成Fe（CO）4（N2）和Fe（CO）4 H2，说明了该电池的使用。红外光谱表明，N2基团可能占据赤道而不是轴向位置。一旦形成。Fe（CO）4（N2）在几乎等于210 K的温度下与H-2发生热反应，生成二氢化物化合物Fe（CO）4 H2。
A new miniature high-pressure cell has been developed for the spectroscopic study of reactions between organometallic compounds impregnated into polymer films and gases such as N2 or H-2 at any temperature between ambient and 20 K. The use of the cell is illustrated by the photochemical reactions of Fe(CO), in polyethylene film (PE) with N2 and H-2 at 190 K to form Fe(CO)4(N2) and Fe(CO)4H2 respectively. IR spectra suggest that the N2 group may occupy an equatorial rather than an axial position. Once formed. Fe(CO)4(N2) is shown to react thermally with H-2 at almost-equal-to 210 K to yield the dihydride compound, Fe(CO)4H2.
