Welcome to the UP Diliman NMR Facility
NMR Facility Information
The NMR machines housed at the Institute of Chemistry, University of the Philippines Diliman were acquired in 2011 through the PharmaSeas Marine Drug Discovery Research Program funded Department of Science and Technology. Inaugurated in 2012, the NMR facility hosts the 400MHz and 500MHz Varian NMR Spectrometers. This facility is a service laboratory which conducts routine 1D and 2D NMR experiments for different projects in the academe and industry. The 400MHz NMR Spectrometer is equipped with a 5-mm One NMR probe and autosampler. The 500MHz NMR Spectrometer is currently equipped with a 3-mm triple resonance indirect detection probe.

Samples are submitted at most 2 days prior to your approved schedule to avoid evaporation of the solvent and are submitted with filled out NMR Service Form. Please fill in all the pertinent information such as the user, sample, and experimental information. Kindly accomplish one form per sample.
A minimum basic half hour rate, or 50% down payment, whichever is higher, must be made upon submission of samples. An additional 25% administrative charge will be applied to the total fees. Please pay at the UPD Cashier’s Office.
Guidelines on the NMR Sample preparation
The sample weight should be from 10 to 20 mg for the proton and carbon analysis.
Samples should be dissolved in deuterated solvent and transferred into an NMR tube. The 500 MHz spectrometer requires a 3 mm NMR tube and the 400 MHz spectrometer requires a 5 mm NMR tube.
Ensure that the sample is completely soluble in the deuterated solvent. Otherwise, filter it prior to transferring to the NMR tube.
