This is probably a carbon carbon double bond stretch here. The signal next to it, if this is 1,600, this is 1,700 so this signal is just past 1,700 and it's very strong, it's a very strong signal, so that makes me think carbonyl. So this makes me think carbonyl right here. lending money for commercial property
