Modified mosher's method

WebThis article describes the application of the modified Mosher’s method to a variety of natural products possessing a secondary alcohol for determining their absolute configuration. The method is generally applicable to secondary alcohols with a few exceptions where the hydroxy group is seriously hindered by neighboring substituents. … Web26 apr. 2024 · After some research, I do understand that \u0027 is an apostrophe in Unicode, however, I do not get why it has to be converted to a Unicode as I have seen Json strings that uses ' within a value. I have tried escaping it by adding \ before ' but it did nothing. To sum up my question, is this a normal behavior for serializing an object to Json?
