Mesure des barrieres d'interconversion entre les deux conformeres enantiomeres de torsion par spectrometre RMN 1 H et 13 C. On montre que les substituants electrodonneurs et electroattracteurs en position 4 augmentent et diminuent respectivement la barriere d'interconversion des napthyl-1 amines tertiaires

The present invention provides a method for determining the authenticity of a petroleum hydrocarbon allegedly comprising at least one specific chemical marker, as well as a method for determining adulteration of a petroleum hydrocarbon marked with at least one specific chemical marker. The methods claimed and described herein rely upon the use of specific chemical markers in combination with laser ionization at a wavelength of between about 300 nm and about 370 nm coupled with ion mobility spectrometry or with mass spectrometry.
