We have applied three-pulse transient absorption spectroscopy to investigate the ultrafast photoisomerization dynamics in two symmetric polymethine dyes. Pump–deplete–probe experiments have revealed that the excited state manifold of these molecules contains two closely lying excited states in the dynamic equilibrium. One of these states is emissive, while the other is largely dark. It is the dark state that ultimately results in the photoisomer formation and is the main channel of excited state decay in these dyes. We have shown that excited state populations do flow between these two states and therefore it can be inferred that the photoisomerization pathway is not predetermined by ground state distortions of the molecular structure. The decision whether the molecule will isomerize or not seems to be taken in the excited state. Global analysis of three-pulse transient data allowed us to determine the spectra of the excited and ground intermediate states and build a comprehensive picture of photoinduced dynamics in symmetric polymethine dyes.

Using R.D. Cowan’s computations (1979) and parametric calculations of Meinders et al (1982), old analyses are thoroughly revised and extended at Aligarh, of Zr III by Khan et al (1981), of Nb IV by Shujauddin et Chaghtai (1985), of Mo V by Tauheed at al (1985). Cabeza et al (1986) confirmed the last one largely.Extensive studies have been reported of the 1–e spectra, Zr IV (Rahimullah et al 1980; Acquista and Reader 1980), Nb V (Shujauddin et al 1982; Kagan et al 1981) and Mo VI (Edlén et al 1985). Some interacting 4p54d2levels of these spectra have been reported from our laboratory, also.Detailed spectral analyses of transitions between excited states have furnished complete energy values for J ≠ 1 levels of these spectra during 1970s and 80s. Shujauddin et al (1982) have worked out Nb VI and Tauheed et al (1984) Mo VII from our lab, while Khan et al (1981) share the work on Zr V with Reader and Acquista (1979).

This paper reports the results from Gallup’s global analysis of the likelihood of first-generation migrants, second-generation migrants and the native-born to send financial help in the form of money or goods to others inside or outside their respective country of residence. The findings in this paper are based on more than 450,000 interviews conducted through Gallup’s World Poll in 157 countries in 2012, 2013 and 2014. The sample includes more than 26,000 first-generation migrants and more than 20,000 second-generation migrants. The large sample enables Gallup to analyze first-generation migrants by the duration of their stay in their adopted country and compare their remittance behaviors with second-generation migrants and the native-born.
