I need ur help

Bojidarka B. Ivanova

Mr. Eltouky, by 15N-NMR!

What means 'ur'?

Asad Raza

From which technique tou want to determine?

Zoraida P Aguilar

You can use a combination of IR spectroscopy to determine whether or not you have the amine and then use Mass Spectrometry to establish the fragmentation pattern which will confirm the presence of your tertiary amine.

Shi Bingyue

IR， it has it's characteristic absorption!

Bojidarka Ivanova

thanks to you ( u r) is mean you are

iam sorry

Enver Guler

XPS (X-ray photoelectron spectroscopy) (ESCA) is also an option. But it is mostly for the surface characterization.
