Having the UV absorbance max wavelength would be helpful.
Thanks.
William Johnson Thank you for the suggestion. We would love to include this, however we are reliant on the data our data sources supply us. ChemSpider brings together lots of information from different sources - and all of the data that is supplied to us is included in the record. However, many of our datasources have more information that they do not supply to us. If you look at the datasources for a record (in the Datasources inbox) you will find other sources of information (often with links to the data).
