The discussion highlights the challenges in finding reliable infrared (IR) spectral data for inorganic and organometallic compounds, particularly regarding metal-oxygen and metal-carbon bonds. Users suggest conducting targeted Google searches for specific compounds, such as FeO2, to uncover relevant literature and IR spectra. It is noted that the US Government has previously published many spectra, although details are scarce. Additionally, researching original synthesis papers of specific organometallic compounds may yield useful data, as these often include reviews with comprehensive information. Participants encourage sharing any successful search results to aid others in similar inquiries.
