MonographDOI
Rotational Spectroscopy of Diatomic Molecules
John M. Brown,Alan Carrington +1 more
TL;DR: Brown and Carrington as discussed by the authors developed the theory behind the energy levels of diatomic molecules and then summarised the many experimental methods used to study their spectra in the gaseous state.
Journal ArticleDOI
The labeling of parity doublet levels in linear molecules
John M. Brown,Jon T. Hougen,K.-P. Huber,J.W.C. Johns,I. Kopp,Hélène Lefebvre-Brion,Anthony J. Merer,D. A. Ramsay,J. Rostas,Richard N. Zare +9 more
TL;DR: The rotational energy levels of diatomic and linear polyatomic molecules often occur in closely spaced pairs of opposite parity as discussed by the authors, and the lower levels of each pair usually form a characteristic set (for example, it may be possible to describe them all with a single energy level expression).
Journal ArticleDOI
Cellular differentiation hierarchies in normal and culture-adapted human embryonic stem cells
Tariq Enver,Shamit Soneji,Chirag Joshi,John M. Brown,Francisco J. Iborra,Torben F. Ørntoft,Thomas Thykjaer,Edna Maltby,Kath Smith,Raed Abu Dawud,Mark Edmondson Jones,Maryam Moghaddam Matin,Paul J. Gokhale,Jonathan S. Draper,Peter W. Andrews +14 more
TL;DR: It is shown that the gene expression programmes of the adapted cells partially reflected their aberrant karyotype, but also resulted from a failure in X-inactivation, emphasizing the importance in adaptation of karyotypically silent epigenetic changes.
Journal ArticleDOI
Imidazo[1,5-a]pyridine: a versatile architecture for stable N-heterocyclic carbenes.
Manuel Alcarazo,Stephen J. Roseblade,Andrew R. Cowley,Rosario Fernández,John M. Brown,José M. Lassaletta +5 more
TL;DR: Rh(I) mono- and biscarbenes from imidazo[1,5-a]pyridin-3-ylidenes (ImPy) and derivatives such as 13 from a mesoionic carbene were synthesized and characterized.
Journal ArticleDOI
Mechanistic and synthetic studies in catalytic allylic alkylation with palladium complexes of 1-(2-diphenylphosphino-1-naphthyl)isoquinoline
TL;DR: In this article, a series of Pd allyl complexes are shown to be highly reactive catalysts for the reaction between (E,E)-1,3-diphenyl-2-propenyl acetate and dimethyl malonate ion; the enantiomer excess varies between 67% and 98% depending on how the reaction is conducted.
