New iisledovaniya report that the trail left by the spirits, can lead to the solution of the crime. Scientists have found that the chemical components of the fragrance can be transmitted from one person to another even with minimal contact. The fragrance leaves a “signature” on clothing for a few days

The team states that it is only a project to test the concept, but after some time, the traces of perfume can be used as evidence in the investigation.
the researchers, who published their work in the journal ,, Science and Justice “, say ., that the spirits will help to solve the crime, which was a close bodily contact, such as rape Main researcher Simon Gergel, who works at University college London, he said: ,, We have decided that the study has great potential, as 90% of women and 60% of men are spirits . There have been many studies in the field of transmission fibers and gunshot residues during physical contact, but no one on the theme of perfume transmission component “.
The spirits are composed of many chemical components, which in combination provide a unique smell. During the study of one bottle of male perfume researchers have discovered that some components are easily leave traces on the cotton cloth and transferred to another. If the two pieces of material have been compressed at least at the moment, 15 of the 44 components of the “transition” from one tissue to another. If the contact lasted up to 10 minutes, then passed 10 elements. Scientists also monitor how time affects the transfer of organic compounds.
They found that if after a person has passed sprinkled perfume 5 minutes, then transferred to another component 24 of 44 after 10 minutes of contact. After 6 hours after spraying perfume – 12 elements, and after 7 days passed 6 volatile compounds
Dr Ruth Morgan, director of the Centre of Criminology College London, said: ,, It is a trial study.. We have shown that, firstly, the transmitted traces from the spirits, and secondly, we can identify the time when the transfer has occurred. In the future it will be possible to determine which contact was between the people “.
However, the research team added that traces of perfume should be detected immediately after the crime, otherwise there will be confusion. They also said that traces of perfume is not . may be been deployed as the sole proof of
Dr Morgan said: ,, It will not be a means of providing some evidence to solve crimes, in most cases, should be carried out several lines of investigation are needed both DNA and fingerprints. and traces of perfume. “
