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.

 Guidelines on the NMR Sample submission

1. Check the NMR Calendar to view the available schedule. To reserve a slot, kindly send an email to This email address is being protected from spambots. You need JavaScript enabled to view it.. Reservations are allocated on a first-come, first-served basis.

2. 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.

3. 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.

4. All experiments that will require more than 30-minute run time will be run during the night queue with a 50% discounted rate on a 2-hour block schedule.

5. Data files will be available 5 to 10 working days from the actual analysis date.

6. Samples submitted will be disposed of after one month if not claimed.

Guidelines on the NMR Sample preparation

1. The sample weight should be from 10 to 20 mg for the proton and carbon analysis.

2. 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.

3. Ensure that the sample is completely soluble in the deuterated solvent. Otherwise, filter it prior to transferring to the NMR tube.
