Furthermore‚ modern software algorithms help to obtain quantitative analysis. This technique works on the fact that bonds and groups of bonds vibrate at characteristic frequencies. A molecule that is exposed to infrared rays absorbs infrared energy at frequencies which are characteristic to that molecule. Then‚ the resulting FT–IR spectra are compared and matched with known signatures of identified materials in the FT–IR library (Bruni et al. 1999). Case study Pigment samples

Abstract In this experiment‚ the nature of linkage isomers will be observed on the example of nitritopentaamminecobalt(III) Chloride and nitropentaamminecobalt(III) Chloride. Their relative stability will be compared on standard conditions and the infrared spectroscopy of both the isomers will be obtained to analyze the characteristic absorption bands for the nitro and nitrito group. Yield for nitritopentamminecobalt(III) Chloride was obtained to be = 1.9221 g(73.24 %) and yield for nitropentamminecobalt(III)

Comparing these values with the literature melting point of 262 - 264°C shows that the product was indeed 9‚ 10-dihydroanthracene-9‚ 10-α‚ β-succinic anhydride and that recrystallization yielded a purer product. Upon examination of an infrared spectrum of the product and comparison with anthracene and maleic anhydride spectra‚ it was found that the product spectrum had similarities with both the anthracene spectrum and the maleic anhydride spectrum. This indicated that the product was

New forensic laser technique for hair analysis Using a new laser technique‚ Jim Moran and his colleagues at Pacific Northwest National Laboratory‚ have devised a method of separating out the parts of hair samples that can reveal details about the recent history of the person to whom it belongs. In their paper‚ published in Rapid Communications in Mass Spectrometry‚ they describe a process they’ve devised whereby hair samples are pulled apart‚ rather than burned as a whole before being measured

Home is Where the Heart is In Ghost Hunter’s recent episode Home is Where the Heart is‚ the ghost hunter team heads to Beardslee Castle in Little Falls‚ NY. Some interesting facts about this castle is that the owner had hanged himself in the house. Along with the hanging other individuals have died in the house. The team investigates to see if they can debunk any of the reported occurrences. The Ghost Hunter team wires the castle/restaurant with video surveillance equipment. By doing this
