Default C-C coupling constants measurement

C-C coupling constants measurement

Hello,I'm trying to set up an experiment to measure C-C coupling constants:1. Do I understand it right that the standard 1D INADEQUATE pulse sequence inad1d would give me quite and accurate measurement of 1J(C-C) constants and the resulting spectrum can be treated similarly to a regular 1H spectrum, i.e. if the carbon in question is a secondary one, its signal will come out as a doublet of doublets?
2. What's the easiest method to measure long-range C-C coupling constant? I have read about SELINQUATE, J-modulated ADEQUATE, GRECCO and modified refocused INADEQUATE (JMR A vol. 122, 245, 1996), but I could not find any of these in the standard Bruker pulse program list. How to set up any of these? Thank you for your time!
