    Sammanfattning : Popular Abstract in Swedish I Nationalencyklopedin står det att spektroskopi är en metod för att studera molekyler, atomer och atomkärnor med hjälp av dess spektra. Man använder både elektromagnetisk strålning och partikelstrålning inom spektroskopin. Spektroskopi används inom astronomi, kemi, fysik och medicin. LÄS MER
