Throughout, the authors address a wide audience, such that this volume may equally be used as a textbook without compromising its research-oriented character. Clearly structured, the text begins with advances in theory before moving on to theoretical studies of chemical bonding and reactivity. There follow separate sections on solid state and surfaces as well as experimental electron densities, before finishing with applications in biological sciences and drug-de 606 $aQuantum theory 606 $aAtomic structure 606 $aMolecular structure 606 $aSolid state physics 608 $aElectronic books. 615 0$aQuantum theory. 615 0$aAtomic structure. 615 0$aMolecular structure. 615 0$aSolid state physics. 676 $a530.12 701 $aMatta$b Che?rif F$0597254 701 $aBoyd$b Russell J$0597255 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910144262603321 996 $aThe quantum theory of atoms in molecules$92054455 997 $aUNINA LEADER 01504nam a2200409 i 4500 001 991000948549707536 005 20020507104243.0 008 950512s1990 it ||| | eng 020 $a8877940336 035 $ab10152295-39ule_inst 035 $aLE00639610$9ExL 040 $aDip.to Fisica$bita 084 $a53.3 084 $a53.3.4 084 $a53.3.5 084 $a53.3.33 084 $a53.3.44 084 $a53.4 084 $a53.4.3 084 $a539.7216 084 $aQC793.5.H32 111 2 $aWorkshop on intense hadron facilities and antiproton physics$0462033 245 12$a1 first Workshop on intense hadron facilities and antiproton physics :$bTorino, 23-25 October, 1989 /$cedited by T.
