Franck-Condon factors and observed band strength distribution in the vibrational structure of the Ag_2 D-X band system

Potential curves for the X_1Σ_g^+ and D_1Σ_u^+ states of three diatomic silver isotopomers, ^(107)Ag_2, ^(107)Ag^(109)Ag and ^(109)Ag_2, were determined from the best available molecular constants by the Rydberg-Klein-Rees method. From these potentials, Franck-Condon factors and band-origin wave numbers were computed, and the reliability of the obtained values was verified by comparison with the observed band strength distribution and the measured band origin positions in a previously recorded D-X spectrum. The ratios of the Franck-Condon factors to those of corresponding isotopic bands were found to be very close to unity, revealing only a very small isotopic effect on the Franck Condon factors of Ag_2 D-X bands. The isotopic shifts of the calculated band origins agree well with previously measured displacements of band heads

Exposure to childhood trauma as a risk factor for affective and psychotic disorders

Introduction: Traumatic experiences in childhood include maltreatment of an individua aged up to 18, which comprises all kinds of physical and/or emotional abuse and physical and/ or emotional neglect, as well as sexual abuse, which lead to the real or potential health hazard. Aim: The aim of present research was to examine the relationship of childhood trauma with symptoms of depression, anxiety and stress in the general population, as well as to compare the exposure to childhood trauma among the three groups of subjects: non-clinical population, clinical population with affective disorders and clinical population with schizophrenia spectrum psychosis. Materials and methods: Medical documentation of 179 adult subjects (healthy controls 92, affective disorders 35 and subjects with psychosis 52) was retrospectively analyzed, using Childhood Trauma Questionnaire, Depression Anxiety Stress Scale and socio-demographic data. Methods of descriptive statistics, between group differences and correlation analysis were applied for the purpose of the data analysis. Results: In the non-clinical sample, a positive correlation between childhood trauma and DASS (depression, anxiety and stress scale) has been noticed (r = 0,265, p = 0,013). When subtypes of trauma were analyzed in this group, it has been noticed that emotional abuse was associated with sub-depression (β = 0,427, p = 0,003), whereas other types of childhood trauma did not influence DASS scores significantly. In addition, we showed that the overall level of trauma did not differ between subjects with psychosis and those with affective disorders. In comparison to the control group, subjects with psychosis had more emotional and sexual abuse, alongside more emotional and physical neglect (p < 0,05). In affective disorders, only sexual abuse was not higher in comparison to the control group (p = 0,390). Conclusion: This research focused on exposure to childhood trauma in patients with affective and psychotic disorders, showing that early adversities have to be considered as a common risk factor in the etiology of the aforementioned disorders. A timely identification of traumatization in childhood and prevention of its consequences by early interventions are important goals of the prevention of mental diroders in adulthood

Franck–Condon factors and observed band strength distribution in the vibrational structure of the Ag2 D-X band system

TPotential curves for the X1Sg+ and D1Su+ states of three diatomic silver isotopomers, 107Ag2, 107Ag109Ag and 109Ag2, were determined from the best available molecular constants by the Rydberg–Klein–Rees method. From these potentials, Franck–Condon factors and band-origin wavenumbers were computed, and the reliability of the obtained values was verified by comparison with the observed band strength distribution and the measured band origin po¬sitions in a previously recorded D-X spectrum. The ratios of the Franck–Con¬don factors to those of corresponding isotopic bands were found to be very close to unity, revealing only a very small isotopic effect on the Franck–Condon factors of Ag2 D-X bands. The isotopic shifts of the calculated band origins agree well with previously measured displacements of band heads
