Smell, taste... oh and the structures are known mostly from spectroscopy, there are several types, and its quite tricky. One example is to break up the molecule by firing electrons at it, and then it is possible to measure the fragments you get by their mass. considering we know the masses of any given atom, you can look at all the different fragment masses and try to piece together what they came from. For example if you see a fragment with a mass of 15 you can tell there is a methyl group (CH3) like those two on the right side of the psylocybin diagram, because C=12 and H=1. Then if you see also a 29, then perhaps that methyl is stuck on to a CH2 in the whole molecule... and so on. |

no,we must all share in this thread-share the love |

why are some chemistry related threads more sucessful than others? |
||||||||

it's a temporary thing. a dip in the force, so to speak |

Just blurting out random facts isnt exactly an discussion starter |

substance detection............? something we use in geology: mass spectrometers - sort out different isotopes of the same element by ionising it and flinging it through an electromagnet in a curved vacuum tube. they cost about £2 million each. they dont let first-years play with it. i wonder why. |

perhaps. and perhaps we could start another couple. just to see what happens. you go first. i'll support you |

so you are a geologist. could you tell me a little about your job? |
