There are two types of SERS mechanisms, which are responsible for the observation of the SERS enhancement [8] one type is the long-range EM effect and the other is the short-range CHEM effect. The EM effect is believed to be the result of localized surface plasmon resonance electric fields (hot spot) set up onto the roughened metallic surfaces [9, 10, 31]. The probe molecules residing within these hot spots will be strongly excited and subsequently emit amplified Raman...

Taradoire condudes that expln results from both the chem effect of the decompn products of H chlorate and the sudden heat produced by the reaction. Androsov et al (Ref 15), in reporting on the catalytic effect of sulfuric acid on the combustion rate and temp rise during flash ign of NC, states that the acid increases the decompn rate up to 250° and concluded that this is because sulfuric acid accelerates NO2 deavage from the NC molecules...
